Shedding Light on Thin-film Solar Cell Efficiency Research




Recently, researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) announced that they have moved closer to creating a thin-film solar cell that can compete with the efficiency of the more common silicon-based solar cell. The Copper Indium Gallium Diselenide (CIGS) thin-film solar cell recently reached 19.9% efficiency in testing at the lab, setting a new world record, according to NREL.

This is still far from the highest efficiency that was achieved in July 2007 by a consortium of researchers led by the University of Delaware (42.8% using a novel technology that adds multiple innovations to a very high-performance crystalline silicon solar cell platform) but of course there are big differences in the manufacturing costs of these two technologies as well as the potential fields of application for them.



The combination of optimizing material systems as well as optimizing processing techniques for these materials gives multiple pathways towards achieving increase in performance from solar cells that can eventually lead to grid parity in terms of cost and efficiency, which seems to be one of the biggest challenges that solar technologies are currently facing.

Solar energy is a mani life for our environment and it is an energy that come from the Sun and it is good solution to create simmilar one

thanks for your posting
