5 - Nonmetal oxide perovskite-based materials (carbon-based perovskites and halide-based perovskites)

Abstract

Over the past decade, perovskite materials have been exploited in the field of novel research for photonic devices such as photodetectors and solar cells. The cost-effective processability and high stability of carbon-based and halide-based perovskite materials have shown great potential for the development of large-scale production processes. Metal halide perovskite materials are also rapidly emerging, and these materials have shown high power conversion efficiency. These materials have been investigated for their extraordinary properties, such as high surface area, tunable band gaps, high absorption coefficients, excellent electrical and mechanical properties, high surface-to-volume ratio, and diversity in the structures. These materials found applications as charge acceptors, transparent electrodes, photosensitive layers, and active light-absorbing materials for developing solar cells and photodetectors. In this chapter, we discuss simple and low-cost processing techniques such as the hydrothermal method, coprecipitation method, sol–gel techniques, gas-phase methods, microwave-assisted methods, and low-temperature methods for the preparation of carbon-based and halide-based perovskite materials. This chapter also presents the full coverage of the recent developments in research of perovskite materials, their related applications, and current challenges, and highlights the concluding remarks and future perspectives.
