Perovskite solar cells have become a hot topic in the solar energy device area due to high efficiency and low cost photovoltaic technology. However, their function is limited by expensive hole transport material (HTM) and high temperature process electron transport material (ETM) layer is common device structure. Numerical simulation is a crucial technique in deeply understanding the operational mechanisms of solar cells and structure optimization for different devices. In this paper, device modelling for different perovskite solar cell has been performed for different ETM layer, namely: TiO2, ZnO, SnO2, PCBM (phenyl-C61-butyric acid methyl ester), CdZnS, C60, IGZO (indium gallium zinc oxide), WS2 and CdS and effect of band gap upon the power conversion efficiency of device as well as effect of absorber thickness have been examined. The SCAPS 1D (Solar Cell Capacitance Simulator) has been a tool used for numerical simulation of these devices.

Abstract Perovskite solar cells have attracted the attention of the researchers in the last couple of years as a potential photovoltaic device. However, the use of expensive hole transport materials (HTM) in these devices often restricts their commercial adaptability. Thus exploring cost-effective, efficient HTL and ETL materials remain an important challenge to the researchers. In this work, simulation studies are carried out considering cupric oxide (CuO), a relatively inexpensive material as hole transport materials for planar heterojunction perovskite solar cells. The photo-voltaic performance of CuO based hole transport layer (HTL) has been estimated in combination with several electron transport materials (ETM) that include TiO2,SnO2,ZnO, CdS, ZnSe,PCBM and Cd1-xZnxS. Studies predict that among these materials, the Cd1-xZnxS electron transport layer (ETL) could be the most promising to result high photo-voltaic efficiency in combination to CuO based HTL. Also, the thickness and optical band gap of perovskite absorber are optimized in order to achieve maximum photo-voltaic efficiency. The cell efficiency of FTO / Cd1-xZnxS/CH3NH3PbI3/CuO/carbon structure is predicted 25.24% under optimized operational conditions with Voc, Jsc and Fill Factor of 1.1eV,26.32mA/cm2 and 87.14% respectively.

Bismuth Perovskite

Theoretical study of methyl-ammonium bismuth halide perovskite solar cells, (CH3NH3)3Bi2I9, was carried out using a one-dimensional Solar Cell Capacitance Simulator (SCAPS-1D) software. The performance of the tested device architectures largely depends on the thickness of the absorbing layer, with the combination of electron transport, and hole transport layers. Thus, the bismuth perovskite absorber layer was optimized by varying the thickness and also, the thicknesses of the different charge-transport materials such as Spiro-OmeTAD, copper (I) oxide (Cu2O), and copper (I) iodide (CuI) as hole transport layer (HTL), and phenyl-C61-butyric acid methyl ester (PCBM), poly(3-hexylthiophene-2,5-diyl) (P3HT), zinc oxide, and titanium dioxide as electron transport layer (ETL). The best performance in terms of the power conversion efficiency (PCE) was recorded for the device with Cu2O as the HTL and ZnO as the ETL with the absorber layer thickness of 200 nm. The working temperature of the device was varied from 295 to 320 K and the effects of temperature on various device architectures were investigated. Results obtained indication that the efficiency of the bismuth perovskite solar cells can be improved by optimizing the thickness of the absorber layer and utilizing an appropriate combination of HTLs and ETLs. Keywords: methyl-ammonium bismuth perovskite, SCAPS, HTL, ETL, PCE.
