Abstract

We have introduced a novel approach to enhance the perovskite solar cell efficiency by controlling the grain growth and light harvesting properties of perovskite crystallites. Instead of using a mesoporous TiO₂ layer, we have modified the surface microstructuring of the TiO₂ film by dispensing nano assembled TiO₂ submicron structures (nanobeads, NBs) on TiO₂ compact layer. With this new approach solar cell efficiency was improved significantly through an increase in both J_sc and V_oc. This high efficiency is attributed to crystallite size of the perovskite phase. These also act as light scattering centers giving higher current density and reduced recombination effects giving higher open circuit voltage.
