In OSCs, photogenerated excitons (electron-hole pairs) are separated into free charge carriers (electrons and holes), transported to their respective electrodes, and collected to produce an electric current.

Near-infrared light detection is promising in medical areas like biometric fingerprint pulse oximetry and non-medical fields like optical communication and night vision. OPDs are attractive for their wide absorption spectrum, mechanical softness, and large-scale solution processing.

A photocatalyst is a substance that can facilitate a chemical reaction through the absorption of light energy to create electron-hole pairs which interact with other molecules, resulting chemical reactions that would not occur without the photocatalyst and light energy. Photocatalysts have wide applications in the field of environmental remediation, for emample, green hydrogen generation and waste plastic recycling.
