Perovskite Solar Cells-Hybrid Devices: Thermoelectric, Electrochemical and Piezoelectric-Connected Power Packs
Findings and reports in the field of perovskite solar cells (PSCs) are phenomenal and embrace diverse perspectives from technical issues, yielding, marketing to environmental concerns. Bottlenecks in structure, manufacturing, and operation of PSCs have been frequently addressed; using various means including crystallography and kinetics study, simulation, material, solution and surface/interface engineering, and their outcomes today result in 23.7% certified efficiency. However, short lifecycle, large waste-to-harvest ratio, function failure in bending and dark-mode, environmental and stability issues, and lack of power storage hinder their commercial viability. As a remedy, PSCs are joined with one or multiple mechanical or thermal energy harvesting or electrochemical power storage devices which fully or partially overcome these non-idealities. Here, the means of integrating different devices with PSCs to form hybrid packs are discussed. The factors contributing to the efficiency and mechanical robustness of PSCs and their hybrid devices upon integration are reckoned. As an essential bridging component, carbon electrodes are also given attention. Furthermore, due to the pressing standards in the energy sector, hybrid devices with non-toxic lead (Pb)-free perovskites should make ideal power packs. Therefore, with reference to their lattice model, optical characteristics and resulting photovoltaic (PV) performance, they have also been briefly highlighted.
