First Solar Inc. (Nasdaq: FSLR), the Arizona company which has been garnering awards almost since its inception (in 1999), announced another milestone on January 16th.

None of the solar cells produced to date shows external photocurrent quantum efficiencies greater than 100 percent from any portion of the solar spectral irradiance band.   

Called the Energy Systems Integration Facility, or ESIF, the laboratory is located at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. The NREL is one of 17 laboratories managed by the U.S.

Research at Lawrence Berkeley National Laboratory (LBNL) has demonstrated a completely counter-intuitive result for thin-film solar photovoltaic (PV) efficiencies, namely that the most efficient solar cells emit more photons than their competitors.

For years, the goal of solar energy has been to extract as much energy as possible from each solar cell, which effectively lowers the cost of the technology as a whole.  

First Solar Inc. (Nasdaq: FSLR), billed as the “world’s most valuable solar company”, has announced a new efficiency record for its cadmium telluride (CdTe) photovoltaic (PV) solar cell.

A partnership between Internet guru Google Inc. (NASDAQ.GOOG) and Solar City, a private company leading the nation in single-source solar photovoltaic power installations for homes and businesses, will see $280 million dedicated to funding residential solar installations, thus making it the largest such fund in the U.S.

U.S. Vice President Joe Biden made a far-reaching promise on May 24. He said that the U.S. is slated to again lead the clean-energy revolution.

At the Argonne National Laboratory in Illinois, a team of scientists has developed a novel way to evaluate the cost of solar photovoltaic (PV) power.
