Sažetak
A new procedure is proposed for the evaluation of the basic parameters of photovoltaic structures, which takes into account the back side reflection and corresponding surface recombination rate. The device response is calculated from the continuity equation¹. Using the generation term which takes into account the reflection both from the front and from the back side of photovoltaic structure², modified expressions for the carrier concentration and current are obtained; using these, the quantum efficiency is determined. Its values, calculated in this way, differ from the ones obtained in the usual way, especially near the absorption edge. The applied technique enables a simple theoretical prediction of the basic parameters of photovoltaic structure.
