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.

基于活淡水绿藻的自供电生物紫外光电探测器
本研究介绍了一种非常灵敏的自供电紫外(UV)光电探测器,利用光合藻类与修饰电极耦合。该装置利用光合作用的绿藻,在自供电操作下实现了卓越的光检测灵敏度和稳定性。值得注意的是,该器件在零偏置条件下对365 nm入射光(最低强度为530 nW cm−2)的响应率和探测率分别为0.44 A W−1和4 ×1010 Jones。此外,它表现出快速的上升和衰减时间,分别为0.15和0.16秒,以优化性能。这种自供电的藻类紫外线光电探测器具有高灵敏度,稳定性和快速的响应/回收率,为可持续社会中紫外线检测应用的当前挑战提供了一个有希望的解决方案。
