Tóm tắt

This study investigates the performance of luminescent solar concentrators (LSCs) using inorganic phosphor films. We examined both single-layer and three-layer stacking configurations on BK7 glass substrates (5 cm × 5 cm × 5 mm), using red, yellow, and green phosphors. Phosphor concentrations ranged from 10% to 50%, with a film thickness of approximately 60 μm achieved through spin-coating. The coated substrates were cured through a series of heating steps to ensure stability. Two experimental groups were established: single-layer and three-layer stacking. Performance metrics including open-circuit voltage (Voc), short-circuit current density (Jsc), and maximum power (Pmp) were measured using a solar simulator. The results demonstrate that threelayer stacking significantly enhances the efficiency of LSCs compared to single-layer configurations, with the optimal arrangement being a red-yellow-green stack. This study provides a detailed analysis of the impact of phosphor concentration, film thickness, and stacking configuration on LSC performance.
