Trends in thin film solar efficiency-CIGS provides over 18% efficiency


CIGS technology among the thin film will  continue to lead the thin-film solar photovoltaics (PV) space. According to a recent report of NREL the CIGS cell have already achieved an efficiency level of 18.8%. Siemens Solar Industries has demonstrated large area modules with a conversion efficiency of >12% using CuInGa(SSe) the viability of Cu–chalcopyrite thin film PV products. Firstgreen team believes that the Development of CIGS cells with improved efficiency will put the thin film technology in forefront in adopting this technology for utility scale solar applications.  Areas where further efficiency gains can be made through the optimization of thin-film deposition process.
