Sustainable and Direct Upcycling of Waste Graphite Anodes via Deep Eutectic Solvents

open access: yesAdvanced Science, EarlyView.
A charged particle attacks the vacancy to realize the in‐situ P‐doping model. Cl− anions chelate with charged metal ions for the purpose of impurity removal, and meanwhile the cations bind to the electrons on the vacancy surface to neutralize the electrons.

Hybrid Perovskite‐Photovoltaic and Solar‐Thermal Harvesting

open access: yesAdvanced Science, EarlyView.
This study presents a hybrid solar energy harvesting concept that integrates a semi‐transparent perovskite solar module with a thermal collector. High‐energy photons generate electricity at 14.3% efficiency, while ≈55% of low‐energy photons provide heat.
