Abstract
The emergence of the new class of organic–inorganic hybrid perovskite materials has found numerous applications in a plethora of next-generation optoelectronic devices like solar cells, light-emitting diodes, photodetectors, and lasers. Synthetic controls of perovskite materials through composition engineering, solvent chemistry, morphology and surface controlling, surface passivation, and band engineering have made the perovskite solar cells the fasted growing technology in the history of solar cells evolution. The perovskite semiconductors possess a number of unique functionalities like easily tunable band-gap energy, solution processability, form long-range crystals at low temperatures (<150 °C), excellent charge transport properties, and self-resistance toward electronic impurity. However, ionic nature and relaxed structural arrangement of the perovskite crystals makes them vulnerable to degradation by moisture and temperature. The stability of perovskite-based solar cells is one of the major roadblocks for their commercialization, though the power conversion efficiency (25.1%) is comparable to monocrystalline silicon solar cells. In this chapter, we will discuss the recent progress in synthesis strategy, structural stability, optical and electronic properties, and evolution in device engineering of the highly efficient perovskite solar cells. We will also elaborate on the future directions to improve stability of the perovskite solar cells.
