Phase Change Materials For Thermal Regulation Of Building Integrated Photovoltaics, Ahmad Hassan
Doctoral
In outdoor deployed photovoltaics (PV), standard test conditions (STC) of 25 °C PV temperature, 1000 Wm-2 solar radiation intensity and 1.5 air-mass rarely prevail. PV temperature can rise 40-100 °C above STC inducing a power drop in crystalline silicon PV with a coefficient of -0.4 to -0.65 %/K above STC. Increased operating temperature also results in accelerated PV degradation due to cell delamination allowing moisture ingress. vConventional building integrated photovoltaics (BIPV) cooling techniques using passive
or active heat removal by air or water flow are limited by (i) very low heat transfer or (ii) large capital as well as maintenance …
