Thermal behavior of parasitic resistances of polycrystalline silicon solar cells

open access: yesRevue des Énergies Renouvelables, 2013
In this work, we investigate the influence of temperature on the series and shunt resistances of polycrystalline silicon solar cells and then to determine the specific expressions of both parasitic resistances as function of temperature.

Spectral Selective and Low‐Noise Thin‐Film Organic Photodetectors Enabled by Electric‐Field Engineering

open access: yesAdvanced Materials, EarlyView.
Molecular doping redistributes the internal electric field in organic photodetectors, providing a new degree of freedom to spatially control carrier transport and collection. Simulations and experiments reveal distinct transport pathways for injected and photogenerated carriers, enabling low dark current under reverse bias and wavelength‐selective ...

Management of maternal ventriculo-atrial shunt malfunction during pregnancy

open access: yesInterdisciplinary Neurosurgery, 2016
Hydrocephalic females reaching childbearing age is increasing due to treatment advances. It has been suggested that ventriculo-atrial (VA) shunts be preferred over ventriculo-peritoneal (VP) shunts during pregnancy.

Pulmonary-to-Systemic Arterial Shunt to Treat Children With Severe Pulmonary Hypertension.

open access: yes, 2021
The placement of a pulmonary-to-systemic arterial shunt in children with severe pulmonary hypertension (PH) has been demonstrated, in relatively small studies, to be an effective palliation for their disease.

Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

open access: yesAdvanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall
