  4. 17. High Bandgap FAPbBr3 Perovskite Solar Cells : Preparation, Characterization, and Application

    Author : Yawen Liu; Erik Johansson; Tönu Pullerits; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 18. Studies of catalyst sintering during operating conditions

    Author : Pooya Tabib Zadeh Adibi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticle sintering; operando spectroscopy; catalyst deactivation; indirect nanoplasmonic sensing; platinum; sintering kinetics;

    Abstract : The damaging effect of pollutants from exhaust gas of combustion engines on the human health and the environment is well recognized. Since the 70s, the three-way catalytic converter (TWC) has substantially improved the urban air quality by simultaneous conversion of CO, NOx and unburned hydrocarbons to O2 , N2 , CO2 and H2O.
