Optimization of Several Parameters Towards 30% Efficiency Perovskite Based Solar Cell Using SCAPS-1D Software

A simulated perovskite solar cell based on a P3HT/MAPbI3/C60 structure is examined to achieve 30% PCE using SCAPS-1D software. Several aspects of the perovskite layer were evaluated, including the perovskite layer thickness, CB and VB effective density of state, band gap, and electron affinity. These factors show great influence on the device performance. The best device based on the best examined parameter has exhibited a PCE of 32.1% correlated with FF of 84.8%, VOC of 1.23V and JSC of 30.77 mA.cm-2. Such a result is promising towards achieving high PCE for perovskite-based solar cells by optimizing several factors, including active layer thickness, energy band gap, electron affinity, and effective state density for CB and VB. However, for the experimentally produced solar cells, the preparation condition and other factors may render this result. A low effective DOS of (1x1016m-3) is desired for both CB and VB to achieve high solar cell performance.
