Are flexible photovoltaics (PVs) beyond Silicon possible?

Recent advancements for flexible photovoltaics (PVs) beyond silicon are discussed. Flexible PV technologies (materials to module fabrication) are reviewed. The study approaches the technology pathways to flexible PVs beyond Si. For the previous few decades, the photovoltaic (PV) market was dominated by silicon-based solar cells.

How did Xiao et al use a blade coated perovskite layer?

Xiao et al. blade coated high-quality, wide-bandgap perovskite layers by tuning the cesium concentration in a mixed solvent system. They avoided diffusion between the perovskite layers with a tin oxide layer grown by atomic layer deposition that also served as an electron extractor.

Does interfacial benzenethiol modification facilitate charge transfer in perovskite solar cells?

Lu, J. et al. Interfacial benzenethiol modification facilitates charge transfer and improves stability of cm-sized metal halide perovskite solar cells with up to 20% efficiency. Energy Environ. Sci. 11, 1880–1889 (2018). Peng, J. et al. Centimetre-scale perovskite solar cells with fill factors of more than 86 per cent. Nature 601, 573–578 (2022).

Are flexible solar cells the future of photovoltaic technology?

For the previous few decades, the photovoltaic (PV) market was dominated by silicon-based solar cells. However, it will transition to PV technology based on flexible solar cells recently because of increasing demand for devices with high flexibility, lightweight, conformability, and bendability.

Are WBG perovskites suitable for all-perovskite tandem solar modules?

The higher bromide concentration in WBG perovskites leads to variations in crystallization kinetics, and precursor solutions are limited by the low solubility of lead and cesium bromide salts ( 13 ). These constraints hinder the scalable fabrication of high-quality WBG perovskites for all-perovskite tandem solar modules ( 14, 15 ).

How does interfacial recombination affect photovoltage?

The interface effect is essential to improve photovoltage. The accumulation of carriers at the interface will promote the generation of electrostatic interface potential, which is conducive to the Fermi energy level split. The Voc can be directly affected by interfacial recombination caused by surface defects of perovskite.
