Lee Rannals for redOrbit.com – Your Universe Online Researchers have developed recyclable, efficient solar cells using natural substrates from plants like trees. Georgia Institute of Technology and Purdue University researchers wrote in the journal Scientific Reports about how the solar cells can be quickly recycled in water at the end of their lifecycle. The team's solar cells are capable of reaching a power conversion efficiency of 2.7 percent. During the recycling process, the...

DOE/Lawrence Berkeley National Laboratory Why are efficient and affordable solar cells so highly coveted? Volume. The amount of solar energy lighting up Earth's land mass every year is nearly 3,000 times the total amount of annual human energy use. But to compete with energy from fossil fuels, photovoltaic devices must convert sunlight to electricity with a certain measure of efficiency. For polymer-based organic photovoltaic cells, which are far less expensive to manufacture than...

A new breakthrough in solar technology means portable electronic devices such as e-book readers could soon be re-charged on the move in low light levels and partial shading. Scientists from the University of Warwick, in collaboration with spin-out company Molecular Solar, have created an organic solar cell that generates a sufficiently high voltage to recharge a lithium-ion battery directly, without the need to connect multiple individual cells in series. Modules of these high voltage cells...

Controlling “mixing” between acceptor and donor layers, or solar cell domains, in polymer-based solar cells could increase their efficiency, according to a team of researchers that included physicists from North Carolina State University. Their findings shed light on the inner workings of these solar cells, and could lead to further improvements in efficiency. Polymer-based solar cells consist of two domains, known as the acceptor and the donor layers. Excitons, the energy particles...

Brett Smith for redOrbit.com Organic solar cells have long been a promising alternative to conventional solar cells, but their low efficiency, low stability, and low strength have kept them from widespread commercial use. Senior chemist Lin Chen of the U.S. Department of Energy’s (DOE) Argonne National Laboratory hopes to change that by focusing on a key component of the cells, the exciton. According to Chen, excitons are considered a sort of “quasiparticle,” because they...

A new study by a team including scientists from the National Institute of Standards and Technology (NIST) indicates that thin polymer films can have different properties depending on the method by which they are made. The results suggest that deeper work is necessary to explore the best way of creating these films, which are used in applications ranging from high-tech mirrors to computer memory devices. Thin films spread atop a surface have many applications in industry. Inexpensive...

Findings may offer clues to superior performance and guide synthesis of materials with improved properties Detailed studies of one of the best-performing organic photovoltaic materials reveal an unusual bilayer lamellar structure that may help explain the material's superior performance at converting sunlight to electricity and guide the synthesis of new materials with even better properties. The research, published in Nature Communications April 24, 2012, was conducted by scientists at...

Method could pave way for lower cost, more flexible devices Imagine owning a television with the thickness and weight of a sheet of paper. It will be possible, someday, thanks to the growing industry of printed electronics. The process, which allows manufacturers to literally print or roll materials onto surfaces to produce an electronically functional device, is already used in organic solar cells and organic light-emitting diodes (OLEDs) that form the displays of cellphones. Although...

Organic solar cells may be a step closer to market because of measurements taken at the National Institute of Standards and Technology (NIST) and the U.S. Naval Research Laboratory (NRL), where a team of scientists has developed a better fundamental understanding of how to optimize the cells' performance. Prototype solar cells made of organic materials currently lag far behind conventional silicon-based photovoltaic cells in terms of electricity output. But if even reasonably efficient...
