Resistive loading of photovoltaic modules and arrays for long‐term exposure testing [PDF]
Progress in Photovoltaics: Research and Applications, 2006 AbstractThis paper investigates the feasibility of using fixed resistors instead of active maximum power tracking as electrical loads for long‐term exposure testing of photovoltaic modules and arrays. The method of investigation was to compare resistive versus active loading on two modules for which historic current‐voltage data over time were ...

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?
Advanced Materials, EarlyView.How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.
