Solar Cell Advances: Omitting Lead from Promising Cell

Environmentally friendly solar cell advances push forward the ‘next big thing in photovoltaics’ Solar cell electronics appear to be getting friendlier on the environmental side of the spectrum. Northwestern University researchers have developed a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. This research advance provides a low-cost, environmentally friendly solar cell can be made easily using “bench” chemistry — no fancy equipment or hazardous materials. “This is a breakthrough…

NREL Researchers Are Busy with Promising New Solar Material

Light-absorbing perovskite cells show promise as solar material Known as perovskite, the name of this material found in the Ural Mountains may be difficult to pronounce for American English speakers, but the potential it offers as a new solar dell material is considerable. Three scientific papers have already been published about it. Intense research efforts, led by the Department of Energy’s National Renewable Energy Laboratory (NREL), are currently taking place. This informative news release came this morning. Unfortunately, photos and…

Nanowires Provide Great Potential for Better Solar Cells

Better solar cells, better LED light and vast optical possibilities Changes at the atom level in nanowires offer vast possibilities for improvement of solar cells and LED light. NTNU-researchers have discovered that by tuning a small strain on single nanowires they can become more effective in LEDs and solar cells. NTNU researchers Dheeraj Dasa and Helge Weman have, in cooperation with IBM, discovered that gallium arsenide can be tuned with a small strain to function efficiently as a single light-emitting…

Perovskite Solar Cells Bring New Possibilities to Renewable Energy Industry

For those involved with solar energy development, Perovskite appears to be a remarkable new material that features two-way applications. Oxford researchers have discovered the material not only absorbs light, it emits it. Here is the recently released press information. Revolutionary solar cells double as lasers Commercial silicon-based solar cells – such as those seen on the roofs of houses across the country – operate at about 20% efficiency for converting the Sun’s rays into electrical energy. It’s taken over 20…
