Аннотация

This project investigates new geometries of hybrid solar collectors to integrate evaporators in CO2 transcritical heat pump cycles. Three different solar absorber plates are compared: a standard PV plate, a hybrid PV/T plate and a solar thermal absorber plate. The solar absorber plate embeds monocrystalline silicon PV cells. A serpentine stainless steel tube is bonded to the back of the solar absorber plate and two-phase CO2 flows within it. The evaporation of the CO2 gathers thermal energy from the solar absorber plate and helps to reduce the operating temperature of the PV cells, hence maintaining their electrical performance. The overall efficiency of the hybrid photovoltaic/thermal solar evaporator can reach 60.5 % on a sunny day in Montreal, Canada
