Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

open access: yesAdvanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Rear-heterojunction GaInP laser power converter with 59% monochromatic efficiency at 590 nm

open access: yesAPL Photonics
Photonic power converters (PPCs) are devices that convert narrowband light at specific wavelengths into electrical energy based on the photovoltaic effect. They are used in optical power transmission systems, which offer advantages over conventional wire

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

open access: yesAdvanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

Municipal building codes and the adoption of solar photovoltaics

open access: yes, 2022
Conflicting societal goals can lead to national and local policies that are at odds with each other. National policies promoting the adoption of solar photovoltaics may be counteracted by local policies defining the aesthetics of the built environment ...

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Characterising dye-sensitised solar cells

open access: yes, 2009
In today’s society there is a vast and in many cases not fully appreciated dependence on electrical power for everyday life. Furthermore, with growing energy and environmental concerns arising due to fossil fuel depletion and climate change/global ...
