WebJun 30, 2024 · When the light power density varies from 101.04 mW/cm 2 to 0.003 mW/cm 2, the direction of photocurrent first maintains negative but the negative amplitude gradually decreases. The direction of photocurrent changes to be positive when the power density is reduced to 16.89 mW/cm 2. The positive amplitude increases to maximum and … WebSep 23, 2024 · The direction of photocurrent in a p–n heterojunction device can be switched by using different wavelengths of light.
