| Abstract |
|
Solar energy devices based on semiconductor-liquid junction principles represent an impressive and potentially highly useful application of interrrelated technologies. The synthesis of solid state physics, electrochemistry, photochemistry and materials science has allowed these devices to realize great advances in relatively short periods of time. However, rational design and optimization of these systems has proven to be difficult. Recent transient absorbance, electrochemical and quartz crystal microbalance studies on metal oxide variants of these systems have shed new light on the events taking place during energy conversion. Our interpretation of an important subset of these results suggests a paradigm shift concerning interfacial charge-transfer and the thermodynamics of the semiconductor-liquid interface-key factors in the performance of these devices. Presented here are these results and a description of this new model.
