Recently perovskite materials have demonstrated significant potential as solar absorber materials. Long-term stability is a prerequisite for perovskite solar cells (PSCs) to be economically viable. Numerous attempts are being taken to develop non-toxic, cost-efficient lead-free perovskite solar cells with high efficiency. In order to accomplish this, lead-free CH3NH3SnBr3 is seen as a competitive alternative to lead halide perovskites. In this paper, we design and simulate a p-i-n heterostructure perovskite Cu2O/CH3NH3SnBr3/TiO2 solar cell where tin halide perovskite is utilized to overcome the stability and toxicity problem of lead halide. The solar cell's performance has been evaluated by one dimensional simulation software SCAPS (version 3.3.10). We have investigated the effects of temperature, series resistance, optimal thickness of absorber layer, defect density, properties of electron transport material (ETM) TiO2, hole transport material (HTM) Cu2O on efficiency. We obtained maximum efficiency of 25.52% with Voc of 0.93V, Jsc of 33.89mA and FF of 80.23%. These findings indicate that an ecologically friendly and high efficient perovskite solar cell can be developed using methyl ammonium tin bromide (CH3NH3SnBr3).
