3. 27. 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

7. 30. Insights into Electrochemical Energy Storage by use of Nanostructured Electrodes

   Författare :David Rehnlund; Leif Nyholm; Kristina Edström; Fredrik Björefors; Emanuel Peled; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

   Sammanfattning : Template-assisted electrodeposition is a powerful technique for fabricating complex nanostructured electrodes. Through the use of pulsed-electrodeposition nanostructured electrodes of Al, Cu and Sn have been realised and subsequently coated electrochemically with V2O5, MnxO, Li, Cu2O and a polymer electrolyte.
