The perovskites are a promising material for the next-generation of photovoltaics, perovskite solar cells (PSC). Since their discovery in 2009, they have drawn great attention. Alongside their low-cost production, they also possess favourable optoelectronic properties (high absorption coefficient, low recombination rate, high mobility of charge carriers and tuneable band gap). Over the past decade, the power conversion efficiency (PCE) of the PSCs has been significantly enhanced from 3.8% in 2009 to more than 25% in single-junction architectures and more than 29% in silicon-based tandem cells. The most commonly used absorber materials in PSC are methylammonium lead triiodide (MAPbI3) and formamidinium lead triiodide (FAPbI3). The results have shown that FAPbI3 is thermally highly stable making it a most promising perovskite material for single-junction PSCs. Recently, the incorporation of rubidium and caesium cations (Rb+ and Cs+) emerged as a strategy to enhance PSCs efficiency. Following these results, we have synthesised the formamidinium lead triiodide with Rb and Cs (RbCsFAPbI3) as an absorber perovskite layer. Our PSC device consists of several layers, ITO/TiO2/Perovskite/Spiro-OMeTAD/Au, with a power conversion efficiency of 7% [1]. To increase the PCE of our device we have performed numerical simulation of PSC to understand which parameters can affect their performance and the highest PCE that can be achieved. The simulation results, obtained by using solar cell capacitance simulator (SCAPS), will be presented as well as the influence of an additional BaTiO3 layer on the device performance.
