Zinc Grid Based Transparent Electrodes for Organic Photovoltaics

open access: yesAdvanced Energy Materials, EarlyView.
A transparent flexible electrode based on an embedded zinc grid with ≈1 µm linewidth is reported, and its utility as a drop‐in replacement for indium‐tin oxide coated glass electrodes in organic photovoltaic devices is demonstrated. The zinc grids are fabricated using the unconventional approach of condensation coefficient modulation, using a ...

Discerning Blend Microstructure and Charge Recombination for Stable Biorenewable‐Based Organic Photovoltaics

open access: yesAdvanced Energy Materials, EarlyView.
A combination of morphological, electrical, and spectroscopy techniques is used to evaluate the degradation mechanisms of non‐fullerene (NFA)‐based organic photovoltaics (OPVs). Blends based on Y12 are more stable than Y6, aspeciallyOPVs from FO6‐T:Y12 demonstrated superior stability with an extrapolated T80 of over 2000 hours under maximum power point

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

open access: yesAdvanced 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

Beyond Silicon: Toward Sustainable, NIR‐II, and Conformable Organic Photodiodes

open access: yesAdvanced Energy Materials, EarlyView.
In this perspective, a strategic shift in organic photodetector (OPD) research is proposed: instead of the incremental advances in silicon's stronghold arena, the most impactful future for OPDs lies in addressing silicon's intrinsic limitations, i.e., detection in the longer wavelength range above silicon's coverage (>1100 nm, termed as near infrared ...
