Abstract: The main problem of the photovoltaic conversion device is that low energy photons cannot excite charge carrier to the conduction band, so that the concept of the quantum dot solar cell is proposed in the intrinsic region of the p−i−n structure. In this work, numerical simulation has been proposed using the Matlab software. We simulate and measure the effects of quantum dots size and temperature on efficiency of GaAs p−i−n structure solar cells incorporating quantum dots (QDs) InAs under illumination. The results show that the efficiency of p−i−n solar cell depend strongly on size of QDs and temperature.
