| The objective of this research is to develop a new type of hybrid concentrated Photovoltaic/Thermal (CPV/T) solar collector system that could partially fulfill a typical four people family's heat and electricity demands in many parts of the world.;A CPV/T system with a solar collector diameter of 6.18 m, 30 m 2 area along with 1.13 m radius, 4 m2 and solar PV panel with spectral selection of radiation for the two devices is analyzed. The model developed assumes the use of new solar cell panels combined and concentration of solar energy dish that improves upon the efficiency of current photovoltaic thermal (PV/T) systems. With normal beam irradiance incident on the concentrated dish of about 1,000 W/m2 under a clear sky around solar noon in New York city, the concentrated insolation to a notch filter with a transmissivity of 90 percent through which the radiation passes will increase up to 7,500 W/m2 if the area of dish and PV receiver is 30 m2 and 4 m2 respectively. From the spectrally selected solar energy of wavelengths suitable for the PV receiver, about 22 percent of solar insolation (1,910 kWh/m2 per year) will be transferred into electricity, and the rest of energy reflected into a cavity thermal receiver to be used as heat when the average normal beam insolation is 1,286 kWh/m2 per year.;A detailed calculation for electrical efficiency based on the spectrally selected solar energy has been developed in this work. Calculations using Mathematica software indicate that electrical efficiency of non-concentrating system solar cells is about 55 percent using the Shockley-Queisser approach and 39 percent by the device-based method, and for the CPV/T system, the efficiency is 42 percent based on device-based method.;This CPV/T system could provide both electrical and thermal energy to a family of four with an average electrical consumption of about 16,900 kWh per year with about 2,781 kWh of electrical energy and 69 MMBtu of thermal energy per year. |
