Co‐Doping Approach for Enhanced Electron Extraction to TiO2 for Stable Inorganic Perovskite Solar Cells [PDF]

Small Science
Inorganic perovskite CsPbI3 solar cells hold great potential for improving the operational stability of perovskite photovoltaics. However, electron extraction is limited by the low conductivity of TiO2, representing a bottleneck for achieving stable ...

Renewable energies and biodiversity: Impact of ground‐mounted solar photovoltaic sites on bat activity

Journal of Applied Ecology, Volume 60, Issue 9, Page 1752-1762, September 2023., 2023
Ground‐mounted solar photovoltaic developments have a significant negative effect on bat activity, and should be considered in appropriate planning legislation and policy. Solar photovoltaic developments should be screened in Environmental Impact Assessments for ecological impacts, and appropriate mitigation (e.g.

Defects in Hybrid Perovskites: The Secret of Efficient Charge Transport

Advanced Functional Materials, Volume 31, Issue 48, November 25, 2021., 2021
Time of flight currents shed light on the interaction of free electrons and holes with defects in MAPbI3 perovskite. Reconstruction of carrier transport dynamics reveals the effect of defects on diffusion length, lifetime, and mobility. Photo‐Hall and thermoelectric spectroscopies assess parameters of defects.

On the prospect of identifying visible emissions from optical measurements of self-assembled QDs

Results in Materials, 2023
The work presented here focuses on the optical properties of molecular beam epitaxy-grown self-organized InAs quantum dots (QDs). Under low excitation power densities, the photoluminescence (PL) spectrum of the structure under study exhibits a double ...

Unveiling the Electronic Band Structure and Temporal Dynamics of Excited Carriers in Formamidinium Lead Bromide Perovskite

Advanced Optical Materials, Volume 12, Issue 9, March 22, 2024.
With the use of a synergic and multiscale approach that brings together experiments and theory, a detailed insight into the electronic structure of FAPbBr3 along with the description of the ultrafast dynamics of photoexcited carriers is provided. The multiscale methodology allows the exploration of novel strategies for the design of perovskite‐based ...

Insectivorous bats alter their flight and feeding behaviour at ground‐mounted solar farms

Journal of Applied Ecology, Volume 61, Issue 2, Page 328-339, February 2024.
The negative effects of solar farms on bat flight and feeding behaviour should be considered when solar energy projects are planned. Research is needed to understand the mechanisms underlying the effects; for example, shading underneath solar panels may reduce plant biomass and therefore insect prey availability.

Detection of optical emissions from deep localized states in a self-assembled InAs/GaAs QD structure

Applied Surface Science Advances, 2022
This work reports on the optical properties of self-assembled InAs/GaAs quantum dots (QDs) grown by molecular beam epitaxy. A sigmoidal temperature-dependent variation of the bandgap energy of the dots is detected from the photoluminescence (PL ...
