Halide Perovskite Solar Cell Efficiency Improvements: New Device Type Simulation

Abstract

Trihalide perovskite photovoltaic (P-PV) solar cells have a promise to be connected into tandems with inorganic PV systems. In this paper, we present p-i-n GaAs & P-PV cells in either in a series way or parallel connection. Comparisons made for two types of tandems by a non-monolithic connection of two experimental sub-cells and results are being discussed based on simulation analysis. It is shown that the parallel connection is always preferable when the sub-cells photocurrent is not balanced while Voc (open circuit voltage) is close to each other. Total efficiency over 20% is demonstrated for GaAs shading effect by MAPbI3 (methylammonium lead halide) film, with achieved Jsc - 41 mA/cm2 (short circuit current density) and high Voc
