Heat pump-Carnot battery system for residential PV storage Italian researchers have developed a reversible heat pump-ORC Carnot battery that stores surplus residential PV electricity as heat and converts it back into electricity when needed. Simulations showed that optimizing the ORC expander speed could raise round-trip efficiency to 35%, while enabling the system to meet the modeled household’s daily electricity demand.

New subcell current metrology for perovskite-silicon tandem solar cells Fraunhofer ISE researchers developed a millisecond-scale electrical method to separately measure perovskite and silicon subcell currents in tandem solar cells using the silicon cell’s capacitive charge reservoir. The approach can be integrated into standard j–V testing without additional hardware, potentially enabling inline subcell current monitoring in mass production.

AZO-based HJT solar cells more vulnerable to damp-heat-induced degradation, study finds German researchers have found that aluminum-doped zinc oxide-based silicon heterojunction cells are more vulnerable to damp-heat-induced degradation than their indium tin oxide-based counterparts. To address this issue, they introduced a magnesium fluoride capping layer that significantly improved damp-heat stability by slowing moisture penetration and corrosion.
