Recent Advances in Perovskite-Based Solar Cells

Organic-inorganic halide perovskites have a significant impact on photovoltaic devices and the solar-to-power conversion efficiency is considerably high (~20.1%) compared to the present existing organic solar cells (OSCs) and dye sensitized solar cells (DSSCs). For the past 3 years, there has been tremendous improvement in photovoltaic efficiency of perovskites, i.e. ~9.7% in 2012 to 20.1% in 2015. Meanwhile, several fabrication approaches, inorganic and organic hole transport materials and device concepts have been developed for high-performing devices. Nevertheless, some issues have to be addressed to commercialize the pervoskite solar cells. Particularly, stability of these cells is not well documented in the literature so far and this is the noteworthy concern. In this review, fundamental aspects of the perovskite device and recent developments are illustrated to provide high-performance perovskite solar cells with durability.
