A Spanish University has developed a low-cost solar simulator for the characterization of photodetectors and solar cells
Spanish researchers have created a low-cost LED-based solar simulator that illuminates areas up to 25 cm² across 360–1000 nm (UV to near-IR). It enables reliable and economical testing of solar cells and photodetectors, supporting efficiency and degradation studies at small scale. The device is highly useful for R&D in solar materials and offers applications in textiles, cosmetics, plant biotechnology, and smart lighting
