Fu Jen Catholic University, a Taiwan-based educational institution specializing in electrical engineering research, has developed an integrated solar–thermoelectric power generation system to improve efficiency. The system has used an infrared filter, Fresnel lens, deep parabolic concentrator, thermoelectric cooler module, and copper heat pipe heatsink for dual-mode power generation. According to Fu Jen Catholic University, outdoor tests showed the infrared filter has increased photovoltaic output by 50.0% during peak afternoon sunlight. The Seebeck-effect-based thermoelectric generator added a further 5.2% to overall electric output in the demonstrated configuration. Heat piling up on PV panels has been minimized by the design, thus enhancing their lifespan during extended periods of sunlight exposure. Indoor trials confirmed the deep parabolic concentrator has achieved better focusing performance compared with the shallow parabolic concentrator in identical test conditions. In the morning, reflected sunlight was directed to the thermoelectric module, while in the afternoon, shorter wavelengths were redirected to the PV panel.
