Abstract
With the increasingly depleting fossil fuels and soaring environmental issues, the hope for sustainable energy lies in renewable energy sources. Solar energy is a harmless, abundant, and cost-effective energy source and a potential alternative to fossil fuel. Solar cells (SC) can be used to harness and convert solar energy into electricity. Besides the conversion of solar energy, SCs also offer effective utilization of energy. A prominent example is building-integrated photovoltaics (BIPV), where semitransparent SCs can be applied inside buildings to power the indoor appliances. Semitransparent perovskite SCs (ST-PSCs) are an emerging generation of SCs suitable for BIPV applications due to unique optoelectronic properties and high power conversion efficiency (PCE).
We reviewed literature reports on various aspects of ST-PSCs, including device architecture, optical engineering, materials, and applications. ST-SC comprises of a photoactive layer, charge transport layers, and transparent electrodes. A careful assessment of function-controlling parameters has been regarded as a prerequisite to the ST-PSC device fabrication. Optimization of optoelectronic properties such as light-absorption, color tunability, and transparency has enabled ST-PSC to achieve a PCE of 25.2%. Current research focuses on the development of facile fabrication methods, increasing flexibility and stability, cost reduction, and the use of non-toxic materials.
