Recently, significant research interest has been devoted on the fundamental understanding of the underlying mechanism in solar cells and innovation of new photovoltaic materials. Aim of this research work and its impact deals with the structure-property-performance correlation of the alternative materials for photovoltaic application. The multication complex perovskites (ABO3 and A2B'B"O6 type) which exhibit attractive optical properties along with the electrical properties have been explored for the low cost and efficient photovoltaic application. In this respect, lead free double perovskite oxide, La2NiMnO6, has shown a promising photovoltaic performance under AM1.5G solar spectrum.
