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 ...

Quantitative Prediction of Power Loss for Damaged Photovoltaic Modules Using Electroluminescence

Energies, 2018
Electroluminescence (EL) is a powerful tool for the qualitative mapping of the electronic properties of solar modules, where electronic and electrical defects are easily detected. However, a direct quantitative prediction of electrical module performance

Modeling of space charge dynamics in polyethylene under AC stress based on bipolar charge transport model

Materials Research Express, 2020
Space charge dynamics under AC stress is of importance as a majority of high voltage cables are under AC stress, and space charge is the driving mechanism of dielectric degradation under these conditions.

Modelling electroluminescence in liquid argon [PDF]

, 2010
We present Monte-Carlo simulations of electron transport through liquid argon motivated by our recent observation of electroluminescence light emanating from a thick gaseous electron multiplier (THGEM) in a liquid argon volume.

Thermoradiative Diodes Using Black Phosphorus van der Waals Materials

Advanced Energy Materials, EarlyView.
We demonstrate thermoradiative diodes based on black phosphorus (bP${\rm bP}$)/molybdenum disulfide (MoS2$MoS_2$) van der Waals heterojunctions which generate power by exchanging photons with a colder environment. The bandgap of black phosphorus is well positioned to exchange photons with outer space through the mid‐wave atmospheric window.

Nickel‐Free Perovskite Solar Cells Enabled by Self‐Assembled Monolayers: A Pathway to Efficient and Recyclable Devices

Advanced Energy Materials, EarlyView.
Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...

Electroluminescence from bipolar resonant tunneling diodes

, 1992
The incorporation of an AlAs/GaAs resonant tunneling structure inside a GaAs p-n junction leads to strong quantum-well electroluminescence originating from electron and hole tunneling into the resonant tunneling structure. A large peak-to-valley ratio of
