Comparative Simulation of the Perovskite Solar Cell
Photovoltaic solar cells are the most important device of renewable energy, Silicon based junction solar cells present efficiency lower than 25%. Therefore, researchers switch to new materials to improve the solar cell performance. In recent years perovskite materials have aroused great interest in optoelectronic and microelectronic devices because of their excellent performance, Low production cost and high absorption. Among these materials, the methylammonium tin triiodide CH3NH3SnI3, and: the Methylammonium lead halide CH3NH3PbI3 which are considered to be ones of the best choices for photovoltaic applications, the efficiency of perovskite solar cell has been significantly enhanced from 5.44 % in 2014  to 23.36 % in 2016 [2,3].
