Abstract:

Due tothe present globalunderstandingabout utilization ofrenewable energysources as constantcleanones, PVpowerhas beenthefocused bymanyresearch centers. Research of developmentofPhotovoltaic Energyis generally done in tow fields:reducingcosts andincreasing 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%.Thispaper examines theperformance ofnanostructuredCIGSsolarcellsare 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.
