Photovoltaic-thermal solar air heater based on PCM cylinders, air convection
Researchers in Malaysia designed a photovoltaic-thermal system that can be used in solar drying, space heating, rooftop systems, and off-grid thermal applications. It relies on a double-pass cooling technique based on air convection and phase change material that can reportedly increase PV efficiency from 7% to 9% and thermal efficiency by 31.45%.
