Improved Hole Transport Layer Surface by Carbazole Ammonium Treatment for 988 nm Near‐Infrared Tin‐Lead Perovskite LEDs

open access: yesAdvanced Electronic Materials, EarlyView.
Carbazole ammonium molecule treatment on PEDOT:PSS hole transport layer endows improved tin‐lead perovskite crystallization and interface transport for near‐infrared LED devices. ABSTRACT Incorporating tin (Sn) and lead (Pb) into metal halide perovskites is an effective strategy for reducing bandgap energy, enabling applications in the near‐infrared ...

Core and π‐Bridge Engineering to Deconstruct Y6‐Series into Modular Non‐Fused Acceptors: DFT‐Guided Structure‐Property Map for Organic Solar Cells

open access: yesAdvanced Electronic Materials, EarlyView.
The rigid fused backbone of Y6‐series acceptors is deconstructed into a modular, non‐fused A‐π‐A′‐π‐A architecture. Comprehensive quantum chemical simulations reveal that strategic core and π‐bridge engineering preserves strong near‐infrared light‐harvesting and enhances intramolecular charge‐transfer character.

Pairing Non‐Fullerene Acceptors With the Right Polymer: Impact of Phase Morphology and Short‐Range Transport on Charge Generation

open access: yesAdvanced Electronic Materials, EarlyView.
This study investigates polymer requirements for pairing with high‐efficiency non‐fullerene acceptors (NFA) in organic photovoltaics by comparing three polymer blends across varied phase morphologies. The generation of free charges is driven by fast transport‐assisted charge separation combined with slow intrinsic recombination.

Selenium Thin-Film Solar Cell

Japanese Journal of Applied Physics, 1982
A new selenium thin-film solar cell of superior performance has been developed. The cell incorporates an SnO2/CdSe/Se/Au structure and is fabricated at 250°C or lower by vacuum evaporation only. The maximum efficiency is attained at 60°C, and its value is 4.6% for an AM 1 (Air Mass 1), 100 mW/cm2. This indicates the possibility of using the cell at

Microcrystalline Organic Thin‐Film Solar Cells

Advanced Materials, 2013
Microcrystalline organic films with tunable thickness are produced directly on an indium-tin-oxide substrate, by crystallizing a thin amorphous rubrene film followed by its use as a template for subsequent homoepitaxial growth. These films, with exciton diffusion lengths exceeding 200 nm, produce solar cells with increasing photocurrents at thicknesses
