Characterization of Aerosol Deposited Cesium Lead Tribromide Perovskite Films on Interdigited ITO Electrodes
These, Albert; Khansur, Neamul H; Almora Rodríguez, Osbel; Luer, Larry; Matt, Gebhard J.; Eckstein, Udo; Barabash, Anastasia; Osvet, Andres; Webber, Kyle; Brabec, Christoph J. John Wiley & Sons (2021-01-15)Aerosol deposition (AD) is a promising additive manufacturing method to fabricate low-cost, scalable films at room temperature, but has not been considered for semiconductor processing, so far. The successful preparation ... -
Ion-mediated hopping electrode polarization model for impedance spectra of CH3NH3PbI3
Almora Rodríguez, Osbel; González Lezcano, Alfredo; Guerrero, Antonio; Brabec, Christoph J.; Garcia-Belmonte, Germà American Institute of Physics (2020-08-18)Methylammonium lead iodide (CH3NH3PbI3) is one of the most attractive materials for optoelectronic applications, and it is the most typical absorber in perovskite solar cells, which are unprecedentedly successful devices ... -
