Photosynthesis holds the key to the efficient use of solar energy by humans using abundant and renewable materials. At the heart of photosynthesis, the pigment-protein complex photosystem II reaction center (PSII RC) performs charge separation with near unity quantum efficiency despite its highly disordered energy landscape, and thus converts sunlight to electrochemical energy.

To achieve this amazing feat, the PSII RC exploits the Quantum Design Principles of Photosynthetic Charge Separation1-2, complementary and interrelated solutions to ensure rapid forward and irreversible transfer of energy and electrons within a disordered and fluctuating environment. Therefore, these principles provide a guide for the rational design and construction of systems able to transfer energy and electrons with high efficiency and in the right direction.

These principles will be presented, focusing on the key parameters that will lead to the implementation of quantum coherence in bio-inspired systems with the potential to perform efficient energy and electron transfer, with the final goal of achieving the cost-effective conversion of solar energy to fuel.
