Morphological and opto-electrical studies of newly decorated nano organo-lead halide-based perovskite photovoltaics

Abstract

In a world where conventional sources of energy are fast depleting, the quest for alternative energy sources may hold the key for the survival of humanity. In the present work, we have tried to generate energy from perovskite-based solar cells. In order to bring this idea into fruition, a newly developed nano perovskite material n-propyl ammonium lead chloride (C3H7NH3+PbCl3−) was chosen and fabricated via co-precipitation pathway. Here n-propyl amine (n-C3H7NH2), and hydrochloric acid and aqueous solution of Pb(CH3COO)23H2O were used as the starting precursors. Acetic acid was added to the solution at the final stage to maintain the optimum pH of the reaction medium and then the solution was gradually concentrated and cooled down to room temperature. Later, the synthesized material was layered on TiO2 film through spin-coating to generate the targeted device. The device then underwent systematic analysis using XRD, SEM, UV and photo conversion to get a transparent idea regarding its structural, electrical and optical properties. When experimentally applied, this newly developed perovskite-based solar cell has generated appreciable amount of energy conversion efficiency (η) and it is around 6.01%. Thus, it can be concluded that this material is an effective building block of efficient solar cells. This technology can be tried in large scale as a source of nonconventional energy in the upcoming days.
