Engineering Slow‐Carrier Interfacial Recombination Enables Tailored Spectral Response

Advanced Science, EarlyView.
This work demonstrates that weak‐drift slow carriers are preferentially captured at generic semiconductor surfaces/interfaces and recombine. This process is manipulated to achieve tailored spectral response. A tens of µm‐wide depletion region is created to observe surface collection rates for photocarriers generated at different positions.

Advances in Se Wide‐Bandgap Photovoltaics and TexSe1‐x SWIR Photodiodes

Advanced Science, EarlyView.
In this review, fundamental properties and current challenges in Se photovoltaics (PVs) for tandem and indoor PVs and TexSe1‐x alloys for short wave infrared photodiodes are discussed. A case is made for the practicality of elemental chalcogenide optoelectronics, and a pathway toward resolving the key challenges in these respective technologies is ...

NbN Broadband Plasmonic Absorbers for Efficient Hot‐Carrier Injection Toward Improved Solar‐to‐Hydrogen Conversion

Advanced Science, EarlyView.
Niobium nitride (NbN) broadband plasmonic metasurface absorbers provide an efficient platform for solar‐energy conversion through hot‐carrier injection. Quasi‐epitaxial NbN features a low work function of 4.0 eV, reducing the interfacial injection barrier and facilitating charge transfer into adjacent photocatalysts.

A Very‐High Frequency Solution‐Processed Organic Field‐Effect Transistor With Improved Voltage‐Normalized Frequency of Transition

Advanced Science, EarlyView.
Increasing the frequency at which organic electronics operate while limiting the operation voltage is key to enabling future sustainable wireless applications. This work shows p‐type organic field‐effect transistors based on a molecularly doped, small molecule/polymer blend (C8‐BTBT:C16IDT‐BT), fabricated via direct‐writing and solution‐processing ...

Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu2ZnSnS4 Solar Cells Enabling High Efficiency and Stability

Advanced Science, EarlyView.
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.
