Light Harvesting Through Citrus × Aurantium Leaf Textured Films

Abstract

Reflection losses in solar energy harvesting devices need to be reduced for increasing their efficiencies. One of the fascinating ideas could be the use of bioinspired surfaces. In this study, we have used the textures found on the leaf of citrus × aurantium (CA) for reduction of the reflection losses and increasing light harvesting efficiency. The results showed that CA leaf-textured surfaces can reduce the reflection losses for almost all wavelengths in the range of 300 nm to 1200 nm. External quantum efficiency measurements revealed that these textures can considerably increase the efficiency within the wave length range of 400 nm to 600 nm.
