Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

High Cooling Rate for LRE123 Stoichiometry Control in Preparation of High‐Tc Bulk Superconductors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review presents the cooling‐rate‐control melt‐growth (CRCMG) method as an effective strategy for regulating LRE123 cation stoichiometry. By accelerating the cooling rate during crystallization, oxygen vacancies are increased in the growing lattice, which suppresses LRE3+/Ba2+ substitution and yields near‐ideal 1:2:3 stoichiometry with enhanced ...

Must Longtermists Wish Us All Dead? A Quadrilemma

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extinction will likely augment total utility among human and non‐human animals ...
