The effect of active layer thickness on the electrical properties of Tin Halide Perovskite (CH_3NH_3SnI_3) was studied using the General-purpose Photovoltaic Device Model (GPVDM) software which is an efficient tool in simulating optoelectronic devices. The simulation was based on some semi-empirical results, and the parameters were inputed to definite materials of each active layer of the solar cell while parameters such as operational temperature and suggestive resistance were based on default entry of the GPVDM simulation software. Absorber thickness was varied from 100nm to 1000nm while other parameters were kept constant. Optimum efficiency of 13.9% was obtained by absorber layer with 600nm thickness, with fill factor and open circuit voltage values decreasing as the absorber thickness increases. Results also showed that the efficiency of this device can be improved by adjusting the active layer thickness.
