AN INTEGRATED EFFICIENT SOLAR COLLECTOR SYSTEM USING PELTIER DEVICES AND WATER STORAGE

摘要

It is known that the semiconductor technology used in both solar cell collector and the Peltier devices have low conversion efficiency which limits their usage to large scale electric energy production. The following application applies 2 phase conversion of a refrigerant medium on the hot and cold side of the Peltier device. The topology improves the efficiency defined as the electric power output of the conversion to the heat energy delivered from the solar collector. The theoretical computations show a large system improvement on energy harvest from heat sources by employing thermodynamic cycle using a refrigerant.
