In the realm of biomedical diagnostics, the development of sensitive and specific detection methods for cancer biomarkers is of paramount importance. Herein, we report on the design and implementation of a self-powered photoelectrochemical (PEC) sensor that harnesses amplified photocathode signals for the deterioration of carbohydrate antigen 125 (CA125) associated with ovarian cancer. This self-powered sensing platform integrates Cu
