Underground heat exchanger to cool down solar panels
Spanish scientists have built a cooling system featuring heat exchangers on solar panels and U-shape heat exchangers installed in a borehole at a depth of 15 meters. The researchers claim that this reduces panel temperatures by up to 17%, while improving performance by about 11%.
Algae could boost solar panel efficiency by 4%
A Swedish team has inaugurated a pilot facility to mass produce algae material that can potentially boost silicon solar module efficiency by 4% and thin film by 36%. The algae are added to the encapsulant in silicon-based modules or to the anti-reflective coating on the glass of thin film modules. The team estimates the resulting modules would be 3.9% cheaper.
