Indoor solar cell weak light power generation

Can solar cells operate efficiently under indoor lighting?

Solar cells This article has been updated Abstract Solar cells that operate efficiently under indoor lighting are of great practical interest as they can serve as electric power sources for portable electronics and devices for wireless sensor networks or the Internet of Things.

Are flexible solar cells suitable for indoor photovoltaic market?

Nature Communications 12, Article number: 3107 (2021) Cite this article Environment-friendly flexible Cu 2 ZnSn (S,Se) 4 (CZTSSe) solar cells show great potentials for indoor photovoltaic market. Indoor lighting is weak and multi-directional, thus the researches of photovoltaic device structures, techniques and performances face new challenges.

How effective is a solvent-engineering strategy for indoor solar cells?

Herein, a facile solvent-engineering strategy is developed for effective suppression of both surface and bulk defects in lead halide perovskite indoor solar cells, leading to a high efficiency of 35.99% under the indoor illumination of 1000 lux Cool-white light-emitting diodes.

What types of solar cells can be used for indoor photovoltaics?

IPVs thereby become a growing research field, where various types of PV technologies including dye-sensitized solar cells (14, 15), organic photovoltaics (16, 17), and lead-halide perovskite solar cells (18 – 20) have been explored for IPVs measured under indoor light sources including LEDs and FLs. Fig. 1. Analysis of Se for indoor photovoltaics.

Are bifacial solar cells suitable for indoor lighting?

Indoor lighting is weak and multi-directional, thus the requirement for photovoltaic differs from that designed for outdoor. To efficiently harvest the indoor energy, the authors designed CZTSSe bifacial solar cells on flexible Mo substrate using double-sided deposition to ensure consistency and to save cost.

Why do c-Si solar cells have low PCE?

Although Si based solar cells have achieved maximum PCE of about 26 % under 1 Sun condition due to its broad absorption spectra, under indoor light conditions, it cannot efficiently work owing to its low band gap of ∼1.1 eV. The PCE of c-Si solar cells is reduced is due to indoor capacitive effect results reduction in fill factor.
