Experimental analysis illustrates the benefits of passive cooling methods for photovoltaic cells, suggesting improved efficiency under controlled radiation.
Key Points
Passive cooling significantly improved open-circuit voltage from 20.25 V to 21.50 V during experiments.
Under uniform radiation of 1200 W/m2, a novel zigzag water channel effectively maintained optimal thermal conditions.
Custom experimental setup with real-time data acquisition monitored temperature and electrical power for accuracy.
Demonstrates that non-electrical cooling methods for solar cells may lead to more affordable efficiency improvements.
