  1. 21. High Bandgap FAPbBr3 Perovskite Solar Cells : Preparation, Characterization, and Application

    Författare :Yawen Liu; Erik Johansson; Tönu Pullerits; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High-bandgap FAPbBr3; additives; defect passivation; dopant-free HTMs; 2D perovskites; carbon electrode; oxygen evolution; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : High bandgap lead-halide perovskite solar cells (PSCs) have gained interest as top cells for tandem solar cells and photoelectrochemical applications due to their suitable energy bands. However, the PSCs have limited stability and performance, and their fabrication in a glovebox and utilization of expensive metal contacts increase the cost and limit their application. LÄS MER

  3. 22. Conducting Polymer Electrodes for Thermogalvanic Cells

    Författare :Kosala Wijeratne; Xavier Crispin; Sawako Nakamae; Linköpings universitet; []
