ABSTRACT

The Sun is the main source of energy on Earth to fulfill the huge demand of energy with the increase of the world population. Photocatalysis, as the renewal energy source coverts the Sun light into the electric or chemical energy and contributes significantly along with environmental control. In the series of different photocatalysis, Hybrid Organic and Inorganic Perovskites (HOIP) have shown remarkable progress since the first realization of production with a Power Conversion Efficiency (PCE) of 3.9% in 2009; the record PCE over 25% in 2019 in solar cell devices. Due to excellent optical, electrical and mechanical properties of perovskite makes it a highly promising photocatalysis not only for solar cells but other electronic devices such as light-emitting diode, transistors, memory, detectors, etc. After the great success of perovskite at the laboratory scale, the next step will undoubtedly be developing scale-up techniques for transitioning small-area devices to large-area modules. This chapter will present a brief overview of perovskite, materials synthesis, branches of perovskites, various device architectures, device engineering and challenges to improve the power conversion efficiency and the potential of perovskites in other electronic applications.
