Design Proposed For A Efficient Thin Film Solar Cell
October 29, 2020 | Leave a Comment
A Penn State research team suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency. Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind the more expensive, crystalline solar cells in efficiency. […]

Radiative Cooler Works Even In Sunshine
October 21, 2020 | Leave a Comment
A joint research team from POSTECH and Korea University has demonstrated a daytime radiative cooling material which exhibits lower temperatures than its surroundings even during the day. Now that autumn is here, there is a large temperature gap between day and night. This is due to the temperature inversion caused by radiative cooling on the […]
