Transparent Colorful Solar Cells Have Arrived!

Transparent Colorful Solar Cells Have Arrived!

Transparent, colorful solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun’s energy into electricity. The cells, believed to be the first semi-transparent, colored photovoltaics, have the potential to vastly broaden the use of the energy source, says Jay Guo,

Solar Cell Degrades in Real Time

Using X-ray imaging, scientists at the Technical University of Munich (TUM) were able to watch an organic solar cell degrade in real time. These new observations will help scientists to find new ways to increase the stability of organic solar cells. Organic solar cells, especially those based on polymers are inexpensive to produce on a large

Piezoelectric Material Helps Transistors Save Energy

Tom van Hemert and Ray Hueting of the University of Twente’s MESA+ Institute for Nanotechnologyhave found a way to “plug” leakage current in transistors by “squeezing” the transistor with a piezoelectric material. This cuts the unnecessary energy losses, potentially increasing the battery life of portable electronic devices. If silicon is squeezed, this affects the freedom of movement of

Which Direction Should Solar Panels Face?

A new study from Austin’s Pecan Street Research Institute finds that residential solar PV panels oriented to the West may have more benefits for homeowners—at least in the summer and in Austin. That research flies in the face of conventional wisdom that PV panels should face South where the amount of sunlight that can hit

Quasi-Random Structures: Making Solar More Efficient?

An international team of scientists, led by researchers from the Universities of York and St Andrews, has developed a new method to increase the efficiency of solar cells. The new approach involves using a new structure called a quasi-random structure and achieves highly efficient broadband light trapping in thin films. A quasi-random structure to maximise

Why Electrical Charge Strips Could Revolutionize Superconductivity

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have identified a series of clues that particular arrangements of electrical charges known as “stripes” may play a role in superconductivity—the ability of some materials to carry electric current with no energy loss. But uncovering the detailed relationship between these stripe patterns and the

In Focus: An ‘Antenna’ for Artificial Photosynthesis

Researchers at Chalmers have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, the researchers have created a system that resembles nature’s own antenna system. Artificial photosynthesis is one of the hot trends in energy research. A large number of the worlds’ energy problems could

Solar Ready to Expolde in NYC

Thanks to solar’s resiliency, falling prices and ability to help out in disasters, New York is anticipating more solar installed in 2013 than ever before in the Empire state and in New York City. That’s based on experts who discussed the “Tipping Point for Solar in New York” at the City University of New York

FUTUREWATCH: Self Assembling PV Cells

Newly published research from Rice University and Penn State show that some polymer-based organic PV devices can self-assemble. The research could make producing organic PV far easier and cost effective in the future. The research, led by Rice’s Rafael Verduzco and Penn State’s Enrique Gomez—both chemical engineers, was recently published in the American Chemical Society’s

Researchers: Nanoscale Coating Improves Solar Efficiency

Scientists from the Aalto University offer yet another way of using nanostructures to improve solar cell efficiency. A new nanoscale coating technique can significantly reduce the losses of solar radiation that occur due to reflection. The new cost-effective photovoltaic material is currently being developed under a research program called “Photonics and Modern Imaging Techniques.” The

Dye-Sensitized Solar Cells Get More Efficient

A dye-sensitized solar cell is simple to make using conventional roll-printing techniques, is semi-flexible and semi-transparent which offers a variety of uses not applicable to glass-based systems, and most of the materials used are low-cost. However its conversion efficiency is less than the best thin-film cells. Scientists at the Uppsala University now propose a new
