| Abstract: | Solar energy is one of the most promising renewable energy sources. One of the major loss mechanisms leading to low energy conversion efficiencies of solar cells is the thermalization of charge carriers generated by the absorption of high-energy photons. These losses can largely be reduced by using downconversion mechanism. The purpose of this dissertation is the possibility of using Er3+ and Yb3+ as downconvertor. A theoretical rate equation model of the Er3+-Yb3+ system are simulated numerically by using python in order to obtain the power conversion efficiency (PCE) and the quantum conversion efficiency (QCE). |
