Unceasing demands for the fabrication of low-cost highly efficient light harnessing devices compelled photovoltaic community to investigate newer materials that has eventually led to the evolution of hybrid perovskite solar cells. Primarily, due to the enticing optical, excitonic, and electrical properties, organic-inorganic lead perovskites are considered as suitable light absorbing materials for the development of efficient solar cells. Arguably, controlling the growth of perovskite structures is one of the interesting strategies to tailor their fundamental properties and exploit their potential in the fabrication of high performance solar cells. We have achieved precise control over the film formation of various organic-inorganic halide perovskites, such as CH3NH3PbI3, CH3NH3PbBr3 and CH(NH2)2PbBr3 using different solution based strategies. The fundamental understanding gained through detailed structural, morphological and spectroscopic studies will be discussed towards unravelling the impact of growth conditions on the properties of the perovskites films and the performance of solar cells based on them.
