Abstract
This study introduces a remarkably sensitive self-powered Ultra Violet (UV) photodetector utilizing photosynthetic algae coupled with modified electrodes. The device achieves exceptional sensitivity and stability in photodetection under self-powered operation by leveraging photosynthetic green algae. Notably, the device demonstrates impressive responsivity, and detectivity of 0.44 A W−1, and 4 ×1010 Jones respectively for 365 nm of the incident light with the lowest intensity of 530 nW cm−2 at zero bias condition. Additionally, it exhibits rapid rise and decay times, clocking in at 0.15 and 0.16 s, respectively, for optimized performance. This self-powered algal UV photodetector offers high sensitivity, stability, and swift response/recovery rates, presenting a promising solution for current challenges in UV detection applications for sustainable society.
