Due to their excellent photo-to-electric power conversion efficiency (PCE) (up to 25.2%) under AM 1.5G (≈100,000 Lux), the perovskite solar cells (PSCs) have received widespread attention in recent years, but the research on their weak light (0–1000 Lux) performances is still rare.
Solar Panel Ratings Explained
For instance, at night, when Solar Irradiance is 0 Watts/m², the solar panel, regardless of its rated power, will produce 0 Watts. However, in some situations, when the Solar Irradiance surpasses 1000 Watts/m², an occurrence known as "Over-Irradiance," a 100-watt
