Theoritcal And Experimental Study Of The Photovolta Ic Effect In Thin Films

In the present study the theory of photovoltaic energyrnconversion is presented. Basic factors affecting conversionrncapability of photovoltaic devices are discussed. Generalrnformula of the minority carrier distribution and currentrndensity across p-n junctions are revised and further developrnto arrive at the over all collection efficiency expression wrnis valid for any thin film photovoltaic cells. Focuss is putrnthe main so lar ce II parame -cers like conversion efficiency anrnspectral response.rnTo the end some experimental works on a singlerncrystal solar cell (FD-K) are made. Emphasio is put onrnestablishing circuits capable of measuring various solar celrnpm'wneters ranging from Si--single crystal cell of lou) efficirnThe results of the measurement are presented in the form Ofrntables and graphs. Conclusions are also made on the re8ultsrnobtained
