Monday 25th April 2016
CIGSe modules in standard industrial formats have not yet attained the record efficiency demonstrated at laboratory scale. One possible cause: defects that reduce the efficiency level can form during the course of fabrication.

The Goal: Make solar cells cheaper by eliminating silver and lead from manufacturingVanessa L. Pool, a postdoctoral researcher at SLAC’s Stanford Synchrotron Radiation Lightsource, with an instrument used to observe how a solar cell’s silver contacts form during high-temperature manufacturing.

  A common criticism of a total transition to wind, water and solar power is that the U.S. electrical grid can't affordably store enough standby electricity to keep the system stable. Stanford researcher Mark Z. Jacobson proposes an underground solution to that problem.
Thursday 10th December 2015
Manufacturers around the world are on the lookout for light-weight and robust materials to use in portable solar cells. The thin but robust germanium hybrid layers provide a real alternative.
Friday 4th December 2015
Florida State University researchers are striving to make solar cells more effective at trapping and using light.

The semi-transparent perovskite solar cell absorbs UV, blue and yellow visible light. It allows red light and infrared radiation to pass through. Based on this principle, a double-layer “tandem solar cell” can be built with an efficiency that is much higher than single-layer solar cells. (Image: Empa)
Thursday 3rd December 2015
Scientists have discovered how to make the electrical wiring on top of solar cells nearly invisible to incoming light. The new design, which uses silicon nanopillars to hide the wires, could dramatically boost solar-cell efficiency.

US electrical grid can't affordably store enough standby electricity to keep the system stable, says researcher
Monday 2nd November 2015
A team of scientists have created solar cells that collect higher energy photons at 30 times the concentration of conventional solar cells, the highest luminescent concentration factor ever recorded.
