The staggering rise in perovskite solar cells (PSCs) efficiency in past years has led to multi-fold advancements. They are promising candidate for aesthetically appealing, electrically and optically efficient building integrated photovoltaics, BIPVs. However, the losses in power conversion efficiency are limited due to the spectral mismatch between the incident solar spectra and absorption range of the active perovskite layer. Besides PSCs’ performance, the photoinduced degradation/instability is also a major concern. This talk is about three cross-dependent aspects: band-gap engineering vs “thinning” for semi-transparent perovskite solar cells, transparent front contact and its effect on PCE and, photon management strategy by down-converting (DC) fluorophores to enhance carrier generation.
The discussion further points out the advantages of perovskites for diffuse light irradiance. It is important for indoor light applications where the incident power is already too low for power generation. The talk will also emphasize on the true challenge in the realization of DC effect. The flux and wavelength dependent PCE study shows the real promise of DC effect in PSCs. Further research is imperative for in-depth mechanistic understanding of the semi-transparent PSCs operations.
