Probing the DOS Band Tail in Amorphous Thin‐Film Transistors via Capacitance–Voltage Analysis
A novel method is presented to quantify the band tail of amorphous semiconductors from capacitance–voltage measurements. The method is tested on Indium‐Gallium‐Zinc‐Oxide transistors of different dimensions. The comparison with alternative optical and electrical techniques demonstrates opportuneties of the method and possible shortcomings for very ...

Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize
