Last year, the company predicted it would exceed 22 percent in 2015. May, 2010. As of now, First Solar has only served the commercial market. Quantum efficiency Èext is the ratio of the number of charge carriers collected by the solar Introduction. Cadmium telluride solar cells (CdTe) is a special and comparably very efficient type of thin film solar cells. CdTe cells efficiency is claimed to be more than 17%, but we need to first understand the technology to learn more about efficiency. Solar Energy Technologies Program Peer Review. Abstract: After a long period of stagnancy for record cell efficiency and several years of growth of the industry, CdTe solar cell efficiency has been rapidly increasing recently. A study has been made to improve the efficiency of CdTe/CdS solar cell. First Solar set a world record for cadmium-telluride (CdTe) photovoltaic (PV) solar cell conversion efficiency, achieving 20.4 percent conversion efficiency certified at the Newport Corporation’s Technology and Applications Center (TAC) PV Lab and confirmed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL)..
