Engineering Quantum Photocells through Donor Multiplicity: Scaling Photocurrent and Power with N-Donor Architectures
The study developed a quantum photocell model inspired by photosynthesis to test how increasing donor molecules affects photovoltaic performance. The findings show that adding more donors causes a superlinear boost in current and power because of collective excitation dynamics and better charge transport, proving scaling the donor network improves device efficiency without lowering voltage.
