USC Researchers Develop Liquid, Printable Solar Cells

Monday, April 30th, 2012

Researchers at the USC (University of Southern California) have developed liquid solar cells that can be printed onto any surface.

The cheap, stable nanocrystal solar cells developed by scientists at USC are just about four nanometers in size, meaning more than 250,000,000,000 of them can fit on the head of a pin. They exist in the form of a liquid ink which can be painted on any clear surface plus can float on a liquid solution. Scientists compare the printing of these liquid solar cells to that of a newspaper.

Researchers Richard L. Brutchey, assistant professor of chemistry at the USC Dornsife College of Letters, Arts and Sciences and USC postdoctoral researcher David H. Webber, who contributed to this project said that a new surface coating made of semiconductor cadmium selenide has been developed for the nanocrystals. International journal for inorganic chemistry Dalton Transactions has published their research as the “hot article” of the month.

Panasonic to Broadcast Solar Eclipse Live Using Only Solar Power

Thursday, April 19th, 2012

On May 21, 2012 Japan will see it first annular solar eclipse in 25 years. To commemorate this occasion, Panasonic has launched “ECLIPSE LIVE FROM FUJIYAMA by SOLAR POWER” project to generate a live broadcast of the solar eclipse from from the top of Mt. Fuji at 3,776 meter-high, the spot closest to the sun in Japan. (more…)

3D Solar Panels Generate 20x More Energy Than Flat Solar Panels

Thursday, March 29th, 2012

Solar power engineering is taking to new heights as researchers around the world invent and reinvent methods to harness solar energy to its best capacity. Until now, improving the performance of photovoltaic cells involved only rearranging the layout of solar panels on a flat surface and bringing down their cost. But now, researchers at the Massachusetts Institute of Technology are working on avant-garde 3D designs that would look beyond the traditional outlook of arranging cells on a flat surface or motorized structures keeping them pointed towards the sun.

New Low-Cost Solar Cells Devised by US Chemical Engineers

Monday, March 19th, 2012

Purdue researcher Rakesh Agrawal is leading work to develop solar cells that might be manufactured using special ink printed onto sheets of a supporting material. The approach could lead to new low-cost solar cells economically competitive with other energy technologies.

Researchers at Purdue University are developing an alternative solution to photovoltaic technologies by manufacturing low-cost solar cells using special ink printed on a supporting material.

With funding from the U.S. Department of Energy, the team of chemical engineers led by Rakesh Agrawal, Purdue University’s Winthrop E. Stone Distinguished Professor in the School of Chemical Engineering, will strive to develop solar cells that could be mass produced at a low cost with limited availability of materials. (more…)
