2021 Adv. Energy Mater. (IF 29.368):
Efficient and Stable n‐i‐p Perovskite Solar Cells - Dopant‐Free Hole‐Transporting Material

Enlitech’s SS-X solar simulator makes the breakthrough possible.

  In July 2021,  the international energy journal Advanced Energy Materials (Impact Factor 29.368) reported a Dopant‐Free Hole‐Transporting Material, which can make n-i-p perovskite solar cells efficient and stable. The authors synthesized spirofluorene-dithiolane molecules in a simple and low-cost way to produce a new type of HTM, SFDT-TDM small molecules. The result showed that SFDT-TDM significantly improved the long-term photostability and storage stability. Enlitech’s Solar Simulator was used in this research and the authors got a significant 21.7% (0.04 cm2) and 20.3% (1 cm2) power conversion efficiency (PCE) for small-area and large-area perovskite solar cells. At the same time, Enlitech’s solar simulator still has the unique function of fully automatic changing the light intensity output (0~100 mW/cm2 with 1% resolution) without changing spectrum. It can perform automatic Sun-Voc testing and analyzing the ideality factor of the solar cells, which is more than 10 times faster the the previous methods (optical filter or power supply output control). The improvement of ideal factor testing speed can greatly accelerate your scientific research development.
