Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
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

Advanced Energy Materials, EarlyView.
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

Hybrid Molecular Photoanodes for Water Oxidation Based on Electropolymerized Cu Macrocyclic Complexes on BiVO4‐WO3

Advanced Energy Materials, EarlyView.
Hybrid photoanodes based on WO3/BiVO4 and Cu‐based molecular catalysts are developed for solar water oxidation. The molecular catalyst enables efficient hole transfer and passivates recombination centers, leading to enhanced photocurrent and long‐term stability.

Determination of Electron Extraction in Semiconductor Photoanodes: Steady‐State and Small‐Perturbation Response

Advanced Energy Materials, EarlyView.
A unified analytical model is developed to consistently interpret the steady‐state and small‐perturbation response of photoanodes, both in the time and frequency domain. By accounting for non‐ideal electron extraction and slow hole kinetics, the model explains key experimental trends in the case of a hematite photoanode and allows extraction of related

Bias‐Dependent Quantum Efficiency Reveals Recombination Pathways in Thin Film Solar Cells

Advanced Energy Materials, EarlyView.
Bias‐dependent external quantum‐efficiency spectra provide three characteristic “fingerprints” that reveal whether charge‐carrier loss in high‐efficiency graded CdSeTe solar cells is dominated by the front interface, the bulk absorber, or the back contact.
