Chonnam National University

Chonnam National University researchers have developed a hot air deposition technique for processing tandem solar cells that is simpler, more efficient and requires no humidity-controlled environment. The team achieved a 23.07% efficiency rating, 65°C & 85°C thermal stability, and a 21.82% efficiency for a practical 1 cm2 cell size. Further development on track for a 29.1% practical efficiency.

Scientists at South Korea's Ulsan National Institute of Science and Technology (UNIST), Chonnam National University and also Pohang University of Science and also Technology (POSTECH) have actually created a special perovskite solar cell that utilizes alkylammonium chloride (RACI) to regulate the development of defects in the perovskite layer.

Scientists in South Korea demonstrated a construction method for perovskite solar cells relying entirely on room temperature, ambient problems procedures. Utilizing an all-inorganic perovskite product, and a spray coated electron transport layer, cells made by the group attained a maximum performance of 19.75%.
