Perovskite Solar Cell (PSC) methylammonium lead halide (CH 3 NH 3 PbI 3 ) base is one of promising solar cell that has inexpensive materials, relatively simple and versatile fabrication high power conversion efficiency (PCE). However, perovskite CH 3 NH 3 PbI 3 has relatively low stability due to very sensitive to polar solvents such as water, where this compound will easily decompose into PbI 2 quickly. Some attempts have been made by researchers to increase the stability for example by adding Hole transport material (HTM) to prevent corrosion of the sensitizer, enhance the resistance to degradation CH 3 NH 3 PbI 3 and improve the stability against moisture. Cuprous oxide (Cu 2 O) is ones of p-type semiconductor with low electron affinity and very high hole mobility that is a potential for hole transport material in heterojunction based solar cells. The aim of this research is to investigate the effect of Cu 2 O thickness as HTM in PCE and stability of perovskite solar cell. The electron transport layer (ETL) of TiO 2 was synthesized by a screen-printing method on fluorine tin oxide (FTO) substrate. Perovskite CH 3 NH 3 PbI 3 was deposited on ETL by one step spin coating, while Cu 2 O was synthesized by Chemical Bath Deposition (CBD) on another FTO substrate with 5 times and 10 times dip. The stability of PSC measured by a comparison between PCE after synthesized and after stored for two months. The increasing of HTM Cu 2 O Thickness raise the PCE and stability of PSC.
