Abstract

The recent trend is that perovskite photovoltaic modules are vulnerable to moisture, oxygen, thermal cycle, UV, and mechanical stress, which seriously affect the working stability of the modules under harsh environmental conditions, thereby hindering the rapid commercialization. In this study, a new self-healing graphene–polymer nanocomposite encapsulant layer is proposed to improve the durability and reliability of perovskite solar modules in extreme climates. The encapsulation system combines functionalized graphene nanosheets into a dynamic polymer matrix, which features reversible covalent and hydrogen bonding interactions, that allows for autonomous healing of the microcracks and interfacial defects formed during service. The addition of graphene enhances barrier properties to moisture and oxygen permeability in addition to enhancing thermal conductivity, mechanical strength, and UV shielding properties. Highlighted are accelerated aging tests conducted at high humidity, high temperature, freeze-thaw, sand exposure and prolonged UV exposure that show a high level of photovoltaic efficiency and structural strength retention even after these exposures, when compared to standard encapsulants. The experimental and simulation outcomes show that the proposed nanocomposite will provide an enhancement in the module’s lifetime, reduction in degradation pathways and increase in the energy yield in desert, coastal and tropical environments. The technology developed is a promising path to highly reliable and commercially viable next generation perovskite PV devices.
