Investigation on a spectral splitting photovoltaic/thermal hybrid system based on polypyrrole nanofluid: Preliminary test

摘要: The present work developed a spectral splitting hybrid photovoltaic/thermal (PV/T) system based on polypyrrole nanofluid. This PV/T can overcome the limitation of temperature in traditional PV/T, and achieve high-temperature thermal output. In this system, nanofluid employed filter absorb solar radiation that can't be efficiently utilized by PV cell unit, convert it into medium-temperature energy. principle methodology experimental design was discussed, effect particle concentration performance investigated as well. not only verifies application potential but also obtains some important rules performance. results indicate efficiency unit itself increases with concentration, decreases simultaneously. maximum overall 25.2%, which 13.3% higher than without filter. More importantly, energy harvested such system. Furthermore, an optimal probably realize efficiency.
