Silicon Solar Cell-Integrated Flexible Retinal Prosthesis for Artificial Vision

Abstract

To date, no flexible silicon solar cell capable of directly converting visible light into electrical current has been developed for use in retinal prosthetic devices. In this study, we successfully fabricated silicon solar cells into small, pixelated structures and demonstrated their potential for retinal prostheses. To minimize surgical incisions during implantation and enhance device stability on the retina, we incorporated a flexible polymer substrate. Our results underscore the promise of silicon solar cells in biomedical engineering, especially for retinal prosthesis applications
