New Solar Cell Raises the Bar for Conversion Efficiency

摘要

In the quest to make solar power a mainstream electrical power generation source, improving photovoltaic cells' efficiency has been the industry's Holy Grail.rnImproved efficiency of solar cells effectively drives down the overall pricernof solar power, since the only costs associated with the technology are for its manufacture, installation and maintenance; the fuel source, of course, is free and unlimited. However, the high costs of the technology-relative to thernamount of power generated-have been the main thing keeping solar from being more cost-competitive in mainstream energy markets.
