Chinese scientists have built a selenium solar cell with an alloyed selenium-tellurium absorber, which reportedly reduces interfacial defects. Under standard illumination conditions, the device ...

Scientists led by the University of Denmark have fabricated a 0.30 cm 2 selenium (Se) solar cell with a world record open-circuit voltage of 0.99 V. “We analyzed the loss mechanisms still ...

The silicon solar cell had an efficiency of 2.3 percent, about five times greater than the selenium cell’s. Chapin immediately dropped selenium research and dedicated his time to improving the ...

Selenium makes more efficient solar cells Date: August 6, 2010 Source: American Institute of Physics Summary: By embedding the element selenium in zinc oxide, researchers have made a relatively ...

Research teams have announced that the use of nickel and selenium in the production of solar cells could make them less expensive and more efficient (Photos: Rob Lavinsky/iRocks.com) View 1 Image ...

Alloying [selenium] with tellurium, which has the same crystal structure and [has a] narrow bandgap, can tune the bandgap and increase the melting point, thus expanding the absorption spectrum and ...

existing space-based photovoltaic cells. This high-efficiency solar technology takes advantage of inexpensive silicon wafers and provides a more robust design for next-generation solar cells in space.

The addition of selenium reduces the bandgap, but this is only part of the story, it appears. Cathodoluminescence – turning the solar cell into an LED – and secondary ion mass spectrometry was used by ...

The selenium solar cells of the late nineteenth century could only convert .4 percent of the incoming sunlight into electricity, hardly enough to power anything electric.

Solar cells are constantly improving on the road to maximum efficiency. Now, three records have been broken by two different devices, including one that pushes the highest overall solar conversion ...

This release is also available in Chinese. College Park, MD (August 3, 2010) -- Call it the anti-sunscreen. That's more or less the description of what many solar energy researchers would like to ...
