Stacked organic solar cells have great potential in terms of photoelectric conversion efficiencyhaveThe photoelectric conversion structure with promising application prospects has a certain promoting effect on the research of organic solar cells. In this article, Hou Jianhui's team developed a tunnel junction composed of electron beam evaporated TiOx and PEDOT: PSS. Smooth and dense TiOx: PEDOT: PSS interface was prepared by electron beam evaporation. In PBDB-TF: GS-ISO/TiO21.76And TiO1.76/PEDOT: In PSS, precise control of O2The evaporation flux is reduced, resulting in efficient electron extraction and low Schottky barrier, ensuring charge recombination between the two sub cells. After research and testing, TiO1.76/The efficiency of PEDOT: PSS tunnel junction stacked organic solar cells is as high as 20.27%, which has passed the certification of 20.0% by the Chinese Academy of Metrology. Therefore, the achievements of Hou Jianhui's team signify the arrival of the 20.0% era in the field of organic solar cells.
It is an honor for our company's Paios multifunctional carrier characteristic analysis system and AA * solar simulator to assist Professor Hou Jianhui's research career. We are very grateful for Professor Hou Jianhui's and our customers' continuous support, and hope that our equipment can have the opportunity to help more researchers move forward.
In this article, when testing the IV characteristics of solar cells, the Hou Jianhui team mentioned that our company's agent, the Japanese SAN-EI, has an AA * solar simulator model XES-70S1 with an effective spot area of 70mm × 70mm.
In this article, when testing the transient photocurrent TPC of solar cells, Hou Jianhui's team mentioned that our company's Swiss Fluxim model is Paios' multifunctional carrier characteristic analysis system.
