Check out our latest publication „Knocking the Stability of Solar Cells with Fluorescent Protein Donors upon Rationalizing Design, Integration, and Mechanism“. We transformed the peripheral carboxyl group of FPs (sfGFP and mCherry) into alkoxysilane groups by a simple sol-gel method that enables a surprising stability of hybrid FPs over 2000 hours in standard devices surpassing the prior-art stability of 200 hours of the biogenic photosensitizer. In addition, photoluminescence spectroscopic studies on different FP-sensitized electrodes along with the chromophore design of sfGFP give beautiful insights into the photo-induced electron donor property of sfGFP. The device efficiency jumped up to 0.35% which further increased to 0.45% with a tyrosine mutation in sfGFP chromophore. We also demonstrated graphene-based electrodes obtained from our Graphene-XT collaborator in the STiBNite ITN network showing a new direction of obtaining „green-device“.
