Alleviating nanostructural phase impurities enhances the optoelectronic properties, device performance and stability of cesium-formamidinium metal-halide perovskites
Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Christian Michael Wolff, Daniel Anthony Jacobs, Austin George Kuba, Mostafa Rabie Shlaly Bahr Othman, Beat Ruhstaller, Anaël Morgane Jaffrès
The technique of alloying FA+ with Cs+ is often used to promote structural stabilization of the desirable alpha-FAPbI3 phase in halide perovskite devices. However, the precise mechanisms by which these alloying approaches improve the optoelectronic quality ...
Royal Soc Chemistry2024Effects of Photon Recycling and Luminescent Coupling in All-Perovskite Tandem Solar Cells Assessed by Full Opto-electronic Simulation
Urs Aeberhard, Beat Ruhstaller
The impact of photon recycling (PR) and of luminescent coupling (LC) on the photovoltaic performance of all-perovskite tandem solar cells is analyzed by the means of optical and full opto-electronic device simulation. Optical processes are assessed using a ...
2024Scrutinizing thermally stimulated current transients originating from trapped charges in organic semiconductors: A drift-diffusion study
Thermally stimulated current (TSC) is a widely used technique to assess trap states and extract their density, energy, and capture rate using analytical expressions. In many cases, the latter are derived from physical models pertaining to inorganic semicon ...
