Extracting individual solar cell data from photovoltaic module electroluminescence images and current-voltage curves

Revista Elektrón
Electroluminescence (EL) imaging is explored as a non-destructive method for quality assessment and characterization of solar modules. Here, we demonstrate the acquisition of dark I(V) characteristics for each individual cell within a solar photovoltaic ...

Modifying Electrochemical Doping in Light‐Emitting Electrochemical Cells With Gold Nanoparticles

Advanced Science, EarlyView.
This study shows that gold nanoparticles placed at an electrode can control how electrochemical doping occurs in organic electronic devices. Particularly, in light‐emitting electrochemical cells, by shifting the light‐emitting region, device efficiency is improved without altering the emissive material. This approach provides a simple and effective way

Beyond the Debye Temperature: A Unified Microscopic Framework for Designing Thermally Stable Red‐Emitting Phosphors

Advanced Science, EarlyView.
Local symmetry engineering in noncentrosymmetric Na3EuGe3O9 generates enhanced Eu3+ local dipoles, enabling efficient light–matter interactions, high quantum efficiency, and exceptional thermal stability. A unified microscopic framework reveals the cooperative suppression of multiple thermal‐quenching pathways, resulting in robust red emission in high ...

Low‐Dimensional Metal Halide‐Organic Interdigitated p/n Heterojunction Solar Cells Enabled by Thiomorpholine Hydroiodide Additive

Advanced Electronic Materials, EarlyView.
Thiomorpholine hydroiodide has been developed for regulating crystallization kinetics and passivating defects of two‐dimensional metal halides, enabling the low‐dimensional metal halide‐organic interdigitated p/n heterojunction solar cells to exhibit an efficiency of 24.27% with excellent stability. ABSTRACT Low‐dimensional metal halides are attractive

Hybrid Two‐Step Inkjet Printing and Dip‐Coating Enable Scalable 30%‐Efficient Perovskite/Silicon Tandem Solar Cells

Advanced Energy Materials, EarlyView.
Adopting a scalable hybrid two‐step deposition process route, textured perovskite/silicon tandem solar cells achieve over 30% power‐conversion efficiency. The process route replaces all non‐scalable spin‐coating steps, including organic precursor deposition, self‐assembled monolayer formation, and passivation layer deposition, with scalable techniques ...
