Title: | Photovoltaic thermal (PV/T) system: Effect of active cooling | Authors: | TEO HAN GUAN | Keywords: | Hybrid photovoltaic /thermal system, manifold design, active cooling,operating temperature,cell efficiency | Issue Date: | 11-Jan-2010 | Citation: | TEO HAN GUAN (2010-01-11). Photovoltaic thermal (PV/T) system: Effect of active cooling. ScholarBank@NUS Repository. | Abstract: | Absorption of solar radiation increases the temperature of photovoltaic (PV) cells, resulting in a drop of electrical efficiency. A hybrid photovoltaic/thermal (PV/T) solar system was designed, fabricated and experimentally investigated in this work. To actively cool the PV cells, a parallel array of ducts with inlet/outlet manifold was designed for uniform airflow distribution and attached to the back of the PV panel. Experiments were performed with and without active cooling. A linear trend between the efficiency and temperature was found. Without active cooling, the temperature of the panel was high and solar cells can only achieve an efficiency of 8 to 9%. However, when the panel was operated under active cooling condition, the temperature dropped significantly leading to an increase in efficiency of solar cells between 12 and 14%. | URI: | http://scholarbank.nus.edu.sg/handle/10635/17723 |
