Temperature regulation of concentrating photovoltaic window using argon gas and polymer dispersed liquid crystal films

Low concentrating photovoltaic (LCPV) system has been studied extensively, which showed excellent potential for the building integration application. However, such a suffers from higher operating temperatures due to concentrated light exposed into solar cell. In this work, two different methods have used regulate temperature of cell without interference any other external mechanism. Two concepts were study cells are: i) use Argon gas within concentrator element, ii) incorporation polymer-dispersed liquid crystal films (PDLC) on top module. both cases, power was improved by 37 mW–47 mW when reduced 10 °C and 4 gas-filled module PDLC integrated module, respectively. addition, effect unique nature reduction short circuit current orientation particle, increased at temperature. The study, therefore, shows greater improving efficiency temperature, need additional pumping as needed thermal
