Abstract:

The recent emergence of perovskite materials has revolutionized the photovoltaic technology and offers solutions to contemporary energy and environmental issues. Moreover, the capabilities of single crystals are far superior to the thin film counterparts. This presentation outlines the growth parameters and crystal kinetics involved in the perovskite single crystal growth process for superior wafer-style solar cell devices. Typically, perovskite solar cells with perovskite in the film form are attractive with their higher performance but, they degrade at faster rate, suffer immensely from a high density of traps and grain boundaries, which markedly limit the potential performance in devices.
