Silicon solar cells lose 0.45% of power for every 1°C increase in temperature. If solar modules could dissipate heat more efficiently, the operating cell temperature would be lowered, increasing the module power output. In this paper, we present findings in using encapsulants with improved thermal conductivity to increase the heat transfer from solar cells into the environment. The outdoor performance of solar modules built with the improved encapsulant shows that 1-2% power gain can be achieved compared with the standard encapsulant. Further, modules with the improved encapsulant are anticipated to have better long-term reliability as compared with the standard encapsulant.
