Analysis of Effects Resulted from Changing the Buffer Layer Material on Optimization of Cu (In_(1-x), Ga)x) Se2 thin Filmsolar Cell (CIGS) and Simulation of Cell Structure

摘要

Due tothe present global under standing about utilization of renewable energy sources as constant cleanones, PVpowerhas been the focused by many research centers. Research of development of Photovoltaic Energyis generally done in tow fields:reducing costs and increasing efficiency. CIGS thin film solar cells are of particular importance among the other types of the same category, due to the flexibility and yields of about 20%.This paper examines theperformance of nano structured CIGS solar cells are discussed. The impact of changing material in the buffer layer of cell structure on electrical properties and the overall performance is evaluated. The optimized efficiency is also determined using simulation tools.
