Abstract
The present invention provides a hybrid solar energy conversion system in which a working fluid is made to flow between an internal photovoltaic array and a transparent top layer, where the working fluid is disinfected by a photocatalytic disinfectant layer provided on a light transmitting surface contacting the working fluid. The working fluid is further contacted with the photovoltaic array for the absorption of heat, and the absorbed heat is extracted via an external heat extraction device such as a water tank or a heat exchanger. Accordingly, the present invention provides an improved solar energy conversion system providing both electrical and thermal power, and further utilizing a portion of the solar spectrum for the photocatalytic disinfection of the working fluid.
