Integrated Devices Combining Perovskite Solar Cells and Energy Storage Devices

Abstract

Perovskite solar cell research has emerged as a focal point of the future energy industry as a result of expanding environmental concerns and significant advancements in solar technology. Perovskite materials offer a variety of advantages as photo-absorbers, including tunable bandgaps, high charge mobility, and process advantages via low-temperature solution processes. Thus, perovskite solar cells have presently attained a power conversion efficiency of 26.1%. However, due to their reliance on light energy, their power output can be inconsistent, making commercialization difficult. To address this issue, integrated devices combining perovskite solar cells with energy storage devices have been devised to provide uninterrupted energy supply and storage without external interference. This review paper provides an overview of the latest trends in the integrated devices and explores their potential application areas. These integrated devices have employed supercapacitors and lithium-ion batteries, with different designs using 4 electrodes and 3 electrodes. Furthermore, integrated devices have been designed using flexible substrates instead of glass substrates, making them applicable to various industries. These integrated devices can be utilized as various energy conversion-storage components, such as electric vehicle batteries and wearable devices.
