Advanced Energy Materials, EarlyView.Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...

The Cauchy problem for a linear parabolic partial differential equation
Journal of Mathematical Analysis and Applications, 1979 AbstractNumerical approximation of the solution of the Cauchy problem for the linear parabolic partial differential equation is considered. The problem: (p(x)ux)x − q(x)u = p(x)ut, 0 < x < 1,0 < t⩽ T; u(0, t) = ƒ1(t), 0 < t ⩽ T; u(1,t) = ƒ2(t), 0 < t ⩽ T; p(0) ux(0, t) = g(t), 0 < t0 ⩽ t ⩽ T, is ill-posed in the sense of Hadamard.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Advanced Energy Materials, EarlyView.Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Enhancing Solid Oxide Fuel Cells Development through Bayesian Active Learning
Advanced Energy Materials, EarlyView.This article presents an active learning approach using Bayesian optimization to calibrate the multiphase‐field model parameters for simulating the aging of Ni‐GDC anodes in SOFCs. By integrating experimental data and navigating through complex parameter spaces, it enhances predictive accuracy and provides insights into microstructural evolution ...

Advanced Energy Materials, EarlyView.Air exposure of the C60 electron‐transport layer (ETL) in p‐i‐n perovskite solar cells causes rapid O2 intercalation, forming deep trap states and altering charge carrier balance at the perovskite/ETL interface, thereby increasing non‐radiative recombination.
