Perovskite PV and Organic PV Bandgap States Analyzing Software

BGSA

　　With the technological development of perovskite/organic solar cells, the open circuit voltage is an extremely important parameter in the research of improving the conversion efficiency of thin film solar cells such as perovskite and organic. The quality of the open circuit voltage will be determined by the bandgap of solar cell materials first. With different structural disorder of materials, lower energy state, called Urbach tail state becomes apparent near the band gap. This tail state is also one of the reasons that affect the open circuit voltage. In addition, for organic solar cells, the charge transfer state directly affects the performance of the open circuit voltage.

　　BGSA is the world’s first integrated bandgap analyzing software for solar cells, including perovskite and organic solar cells. With the test data of PV-EQE, ultra-sensitive EQE, and EL-EQE from Enlitech’s QE-R, FTPS and REPS systems, you can quickly get characteristics of states inside the bandgap of solar-cell-materials. By comparing bandgap states with different control parameters of solar cells, the time for users to analyze data can be greatly shortened. Users can spend more time to focus on the material design and processing research of solar cells.
