Trina Solar claims record-breaking efficiency of 26.58% for TOPCon solar cell
Trina Solar says it has achieved a record efficiency of 26.58% for a tunnel oxide passivated contact (TOPCon) solar cell. The Chinese manufacturer says Germany’s Institute for Solar Energy Research Hamelin (ISFH) has independently verified the result.
Balloon-integrated PV system for emergency power needs at low altitude
Researchers in China have created a balloon-integrated photovoltaic system that reportedly represents a feasible solution for emergency PV power generation in mid-to-high latitudes. It consists of a customized balloon, 19%-efficient thin-film cadmium telluride solar cells, an exhaust valve, control and storage modules, fixed ropes, and a cord reel, as well as an upper hemisphere and a lower arc surface.
