Original abstract

Conventional silicon-based photovoltaic (PV) systems suffer a severe drop in power output under overcast and low-light conditions due to their limited spectral response to diffuse solar radiation. This paper proposes a novel bio-hybrid solar cell architecture that integrates a robust, transparent layer of crystalline or polymer-encapsulated Cryptochrome (Cry) proteins onto silicon substrates. Utilizing the quantum biological properties of Cryptochrome—specifically its high-affinity absorption of scattered blue/UV light and subsequent photoinduced electron transfer via the radical pair mechanism—the proposed system serves as a nanoscale light-concentrating and charge-multiplying layer. Theoretical modeling and simulation demonstrate that incorporating Cry-based photoactive complexes can effectively mitigate the losses caused by cloudy conditions by converting scattered short-wavelength photons into secondary electron streams. This research provides a scalable framework for independent research in bio-photovoltaics (BPV) and opens new pathways for next-generation, climate-resilient solar energy harvesting devices.8
