Perovskite solar cells-A futuristic approach

Commercially predominant photovoltaic cells and devices are majorly derived from silicon or combination of other semiconductor materials. Recently, researchers have invested lot of interest in the third-generation perovskite solar cells which promise to give higher efficiency. The reported literature consists of many fabrication routes for the perovskite solar cells which replaced liquid dye sensitized solar cells and thin film photovoltaic cells. The organic-inorganic perovskite solar cells have unique crystallographic structure that helps to tailor its photoluminescence wavelength which makes them attractive candidates for emitter materials in electroluminescent devices. However, the marketable viability of this generation is still facing many issues from long term thermal stability to segregation of the halides used in perovskite cells. The optimization of the fabrication routes, device architecture, reproducibility and material selection are the various pathways on which the scientists are working to produce low cost and highly efficient solar cells. The review paper reports the advancements in the various perovskite solar cells done so far and improvement in their commercial feasibility.
