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 ...

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 ...

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 ...

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 ...

Titanium-Selenium Solar Cells: The Next Frontier. As if cheaper titanium wasn’t enough, researchers at the University of Tokyo are also developing a titanium-selenium solar cell.

By the 1950s, Bell Laboratories realized that semiconducting materials such as silicon were more efficient than selenium. They managed to create a solar cell that was 6 percent efficient.

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 ...
