The power conversion efficiency of the solar cells based on the kesterite layer grown at a relatively higher N 2 pressure (corresponding to a lower concentration of Se during the initial heating-up stage) reaches 14% efficiency (certified 13.8% efficiency), outperforming the kesterite processed at a lower N 2 pressure (Fig. 1b).
Organic solar cells (OSCs) can be solution-processed on flexible substrates at low temperatures, enabling fast and inexpensive manufacturing. Thus they have attracted great attention in past decades. Huge progress in power conversion efficiency (PCE) has been achieved since advances in material and device engineering (Zheng et al., 2019).
Here we report efficient normal structure organic solar cells delivering promising stability under different conditions, based on PM6:BTP-eC9 blend and AZO/Al cathode. The impact of cathode on device stability is systematically studied by screening the leading electron transporting layers i.e., AZO, PFN-Br, PDINN, and metal electrodes (Al and Ag).
Although efficiency over 18% has been achieved, the real application of organic solar cells is still impeded by inferior stability because of degradation and limited studies. Here we report efficient normal structure organic solar cells delivering promising stability under different conditions, based on PM6:BTP-eC9 blend and AZO/Al cathode.
