<p>Semi-transparent
perovskite solar cells have the competitive edge of being employed for building
integrated photovoltaics due to their aesthetic 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
MAPbBr<sub>3</sub>, 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 band gap as well as with (FAPbI<sub>3</sub>)<sub>0.85</sub>(MAPbBr<sub>3</sub>)<sub>0.15
</sub>perovskites<sub> </sub>for the fabrication of solar cell. DBP based solar
cells yielded competitive power conversion efficiencies as compared to
classical HTMs.</p>
