Abstract
Semi-transparent perovskite solar cells have the competitive edge of being employed for building integrated photovoltaics due to their esthetic benefits as light harvesting windows/facades. Perovskites have received considerable attention in recent years as a thin film photovoltaic alternative, that can also be tweaked for its transparency, evolving from potentially high bandgaps that are suited for semi-transparent solar cell fabrication. Due to the existing trade of between the efficiency and transparency of a perovskite solar cell, tuning the band gap can address this by making a bridge between the aforementioned parameters. We report our findings on the use of a wide-bandgap perovskite MAPbBr3, with a rational energetic level hole transport materials based on polycyclic aromatic hydrocarbon molecules that can be a promising alternative class of p-type material. In the present work, DBP (Dibenzo{[f,f′]-4,4′,7,7′-tetraphenyl}diindeno[1,2,3-cd :1′,2′,3′-lm]perylene was evaluated with high bandgap as well as with mixed (FAPbI3)0.85(MAPbBr3)0.15 perovskites for the fabrication of solar cell. DBP-based solar cells yielded competitive power conversion efficiencies as compared with classical HTMs.

Developed metal halide perovskites [1, 2] have generated a significant interest in the photovoltaic (PV) field, and the current decade has witnessed notable progress in its Electronic supplementary material The online version of this article contains supplementary material, which is available to authorized users.Methylammonium lead bromide (MAPbBr3) was first implemented as sensitizers for titania scaffold in a liquid junction solar cells [13, 14]
A maximum power conversion efficiency (PCE) of 10.61% was reported by Zhang et al, followed by 8.2% PCE by Arora et al FAPbBr3 has a narrow band gap of 2.23 eV as compared with MA-based perovskites (2.32 eV) for the polycrystalline films [20, 21]
We report our preliminary results on the fabrication of MAPbBr3, FAPbBr3, and (FAPbI3)0.85(MAPbBr3)0.15based perovskite solar cells (PSCs) employing DBP as a hole transporting layer deposited in solution
