Can Fluorescent Dye Increase the Efficiency of Solar Cells?
Scientists at Yale think that for some solar cells the future may be fluorescent. While many may believe that the purpose of a solar cell is to absorb light, not to emit it (fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation), it turns out that the [...]
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 [...]
Quantum Dot Solar Cell Efficiency Breakthrough Announced
Quantum dot solar cells, an emerging field in solar cell research that uses quantum dots as the absorbing photovoltaic material, could be significantly advanced by a new technique, developed by University of Toronto Engineering Professor Ted Sargent and his research group. In a paper “Jointly-tuned plasmonic-excitonic photovoltaics using nanoshells,” published in the journal Nano Letters, [...]
Upstate New York Scores New Hands-On Solar PV Lab
Next week we’re incorporating more hands-on exercises into our standard 40-hour curriculum because of a great new solar PV lab at VP Supply in Rochester, NY. The lab allows us to expand the hands-on portion of our Solar PV Boot Camp for our Rochester Solar Training courses. A lot of people think incentives in [...]
Empa Scientists Acheive 20.4% Flexible CIGS Efficiency
A record breaking thin film solar cell has been developed by scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology. A team of researchers led by Ayodhya N. Tiwari at the institute’s Laboratory for Thin Film and Photovoltaics have achieved 20.4 percent energy conversion efficiency for their C.I.G.S. solar cells on flexible [...]
Batteries from Plant Dyes?
A recent research has proved that it is possible to make eco-friendly batteries from plant dyes! Well believe it or not but researchers are in the opinion that the red dye obtained from several plant can be used to make lithium ion batteries. A plant known as madder plant which is being used from centuries [...]
In Focus: Solar From Space
We shall draw solar energy from space, says association of Indian scientists WHILE FESTIVE rabies is coursing through the veins of the world’s Christian nations, the Indian Science Congress Association has gathered to find solutions to pressing matters such as energy. The ISCA event is dedicated to progressive thought, and is attended by science junkets [...]
Solar Cell Efficiency and the “Black Hole for Light”
Researchers at Princeton University led by electrical engineer Stephen Chou, have developed what is being called a “nanostructure sandwich” to trap light and improve the efficiency of organic solar cells by 175%. A layer of metal mesh 30 nanometers thick (A nanometer is about one hundred-thousandth the width of human hair) is placed on top [...]
