From sky back to sky: Embedded transparent cellulose membrane to improve the thermal performance of solar module by radiative cooling

The actual high working temperature severely affects the performance of crystalline Si solar module, and cooling function is favorited. Here we made a wood-based cellulose membrane having good transparent, high emissivity in mid IR atmospheric window, it shows a radiative sky cooling ability. We inv...
