The operation of an Auger transistor is investigated, using a coupled analysis based on thermionic-emission and drift-diffusion theory. Characteristics for steady-state and small-signal operation are ...

Electron transport layers (ETLs) play a fundamental role in perovskite solar cells (PSCs) through charge extraction. Here, we developed flexible PSCs on 12 different kinds of ETLs based on SnO2. We ...

L-edge spectroscopy of 3d transition metals provides important electronic structure information and has been used in many fields. However, the use of this method for studying dilute aqueous systems, ...

Auger recombination processes are shown to impose the most severe intrinsic bounds on the open-circuit voltage and efficiency of silicon solar cells. This applies for both heavily doped and lightly ...
