Seeing light-to-energy transfer in new solar cell materials


Scientists at the U.S. Department of Energy’s Ames Laboratory are now able to capture the moment less than one trillionth of a second a particle of light hits a solar cell (for example: Renogy solar suitcase ) The generation and dissociation of bound electron and hole pairs, namely excitons, are key processes in solar cell and photovoltaic technologies, yet it is challenging to follow their initial dynamics and electronic coherence. and becomes energy, and describe the physics of the charge carrier and atom movement for the first time.

Using time-resolved low frequency spectroscopy in the terahertz spectral region, the researchers explored the photo-excitations of a new class of photovoltaic materials known as organometal halide perovskites. Organometallics are wonder materials for light-harvesting and electronic transport devices, and they combine best of both worlds — the high energy conversion performance of traditional inorganic photovoltaic devices, with the economic material costs and fabrication methods of organic versions.

“These devices are so new and so unique that the mechanism by which a particle of light, or photon, converts to charge carriers and how they move in a concerted way for energy conversion is not well understood, and yet that is the most fundamental processes in in solar cell and photovoltaic technologies,” said Jigang Wang, an Ames Laboratory scientist and associate professor of physics at Iowa State University. “Why is this material so distinct? That has been the big question in the scientific community, and it has led to a fever of research and publication.”

Ames Laboratory researchers wanted to know not only how the generation and dissociation of bound electron and hole pairs, namely excitons, happened in the material, they wanted to find out the quantum pathways and time interval of that event.

“If you look at the natural process, in photosynthesis, it’s an extremely efficient process in some biological molecules, so it’s also very coherent. We see a similar thing in a human-made system of a laser; a laser oscillates in a fixed wave pattern,” said Wang. “If we can measure such a memory in the charge transport and energy migration in these materials, we can understand and control it, and have the potential to improve them by learning from Mother Nature.”

Conventional multimeters for measuring electrical states in materials do not work for measuring excitons, which are electrically neutral quasiparticles with no zero current. Ultrafast terahertz spectroscopy techniques provided a contactless probe that was able to follow their internal structures, and quantify the photon-to-exciton event with time resolution better than one trillionth of a second.

Wang credited the contributions of researchers from multiple areas of expertise across the Ames Laboratory with the significance of the discovery. “This was only possible with the collaboration of experts in material design and fabrication, computational theory, and spectroscopy,” he said. “Having those capabilities in one place is what makes Ames Laboratory one of the most forward looking places in this kind of photonic materials research.”

Time to Sell Online?

Beyond connecting with a new demographic, e-commerce can also be an important way for watch manufacturers to compete with online resellers of pre-owned Invicta watches.

“There’s so much secondhand product on the market. We wanted to be there as a direct connection to the consumer,” said Karl-Friedrich Scheufele, co-president of Chopard, whose United States e-boutique opened three years ago. (Chopard’s online operation has since expanded to Britain.)

Indeed, the proliferation of pre-owned watches online — on sites like Crown & Caliber and Bob’s Watches — can be traced to the 1980s, when men began accumulating timepieces, said Danny Govberg, owner of Govberg Jewelers in Philadelphia, a company established in 1916.

Two years ago, the watch retailing company introduced an app, Govberg OnTime, for iOS and Android devices, designed for people who want to buy, trade and sell new and pre-owned watches.

“In 2009 — one generation later — when gold hit $1,800, women stood in line to sell their gold jewelry, but men did not liquidate their timepieces because the knowledge of what to pay for them wasn’t there,” he said.

“So the men just kept the watches in their drawers. It’s been a 25-year accumulation.”

By offering clients click-to-buy capability, transparent pricing, on-demand education, videos, phone support and, last but not least, a brick-and-mortar showroom complete with a touch-screen TV to explore the store’s online inventory, Mr. Govberg represents a handful of online upstarts showing the primary watch market how omnichannel retailing is done.

A Short History of Amish Quilting Styles


The Amish quilt started around the 1870’s, because of their religious beliefs to stay isolated from the modern world of pleasures and conveniences, quilting was at first a temptation that the Amish women resisted. After realizing the practical use of the quilt, they eventually became a normal part of Amish lifestyle.

The first Amish quilts were very plain with solid dark colored fabric, a lot like the clothing they wore. But their talent for the elaborate designs is what made their quilts famous. After much discussion, in the Amish community, over several years the Amish women slowly made modification to their patterns and colors. This decision, like all the Amish decisions, had to be approved by the Amish Community. Today there is more individual input to how the quilts are designed and what patterns are used to create the unique and beautiful colored hand stitched quilts that we see and love today.

Although the outside world doesn’t understand the Amish community, it is the center of Amish existence. Friends and family work together on projects for the entire community. Such as bringing in the crops, building a barn, this is often called a frolic. Women will gather at a chosen home to do canning vegetables, fruits and jellies. Usually one woman will piece a quilt together, but it is not uncommon to have several women around the quilting frame to help stitch the quilt together; this is often referred to as a quilting bee or quilting circle. This allows the women to do something they love and to catch up on everything that is happening in the community.

The Amish believe a woman’s ability to create and hand stitch a quilt is a gift from God that should be used to its fullest ability. Many of the young girls are taught to start quilting by the age of four years old. This helps to explain why they provide such expert stitching in the Amish quilts.

Today, many consider the unique quilt patterns a work of art. More and more families want their own Amish quilt, not just because of it practical use, but for its artistic value. Amish quilts are often used as a piece of wall décor, wedding gifts, birth of a child and they make a great fund raisers.

The term Amish Quilt is used to describe a quilt with the combination of traditional Amish quilt block patters, and made by an Amish or a Mennonite quilter. The reason for this is because the Amish and Mennonites share similar cultural habits. They lived alongside each other since immigrating to the United States. Their history of quilting and their patterns are the same.

3 Tips on Becoming a Pay-Per-Click Expert


Online advertising is one of those industries that is always taking heat for one reason or another. Some of it is just the nature of advertising, some of it has to do with expectations of the future of internet usage. However, online advertising has been, is and will almost definitely continue to be an integral part of every brand’s advertising stack.

Specifically, pay per click is not going anywhere, which means that every marketing and advertising professional knows that part of their recipe for success (and promotion) is building up their skills in online advertising and becoming a PPC expert.

I’ve used PPC to generate hundreds of thousands of dollars for my own businesses, and so can you. I’m not some kind of guru, wizard or prodigy. In fact, when I launched my first campaign I made a ton of mistakes, lost boatloads of money and almost put my company in bankruptcy.

But I eventually got over the hill and am now an expert in using PPC. It’s a tough journey to become a pro, but the ROI is well worth the struggle. Here are the top three tips for mastering PPC, increasing your brand’s revenue and engagement and being recognized as an expert.

1. Learn the platforms.

The first step to becoming a PPC expert is to become familiar with the major platforms. Until you know how to use the tools, you won’t know what’s possible.

The two pillars of PPC are Google AdWords and Bing Ads. The two systems are similar and both Adwords and Bing Ads offer certifications for their programs. While studying isn’t always the most fun, it is as usual the best way to get ahead in this industry.

Once you’ve learned about what’s available to everyone, consider what platforms would work especially well in your industry. For example, if you work in ecommerce, fashion, home decor or other visually appealing industries, consider looking into Pinterest’s Buyable Pins, which allows users to purchase your products directly from the social media platform.

Remember to pace yourself as you learn — these platforms will be the tools you use to build your campaigns, so you should be comfortable enough with each to factor in each one’s strengths and weaknesses for various uses.

Why Smart Internet Marketers Are Opting for Native Advertising


According to a report on Shopify, global retail ecommerce sales are projected to grow to $3.4 trillion (U.S.) by 2019. This is a huge surge compared to 2015’s figure of $1.548 trillion. Unfortunately, only a small percentage of internet marketers seem to be taking advantage. And many are smart enough to be employing something called native advertising.

Native advertising is any paid content that is made to match the form of the platform it appears on without being disruptive. This may mean promoted tweets on Twitter, suggested posts on Facebook and editorial-based content. It can be presented in the form of a video, an image or an article. And no, it is not the same as content marketing.

How’s that? Content marketing involves finding a way to place the product being promoted within the content provided. In contrast to native advertising, this is relatively obvious.

Native advertising is less obvious. It is not even that focused on product promotion. Instead, it usually comes across as sponsored posts on social media platforms and other sites, as promoted tweets, feature videos on Youtube, suggested reading/viewing and more. Native advertising is designed to blend seamlessly into the style and structure of the content of the page and the website on which it is displayed.

In the words of Vladmir Bashkin, business development director of Adnow, a fast-growing native advertising and content-discovery platform, “Native advertising is the ninja of digital marketing: quiet yet visible, subtle yet effective. And you know that ninjas kick ass; so does native marketing”.

This statement encapsulates the reasons I believe all smart internet marketers should leverage native advertising for their marketing campaigns. Those reasons:
