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. A Chinese research group has developed a portable balloon-integrated photovoltaic system (BIPVS) for low-altitude applications. "The genesis of our research was a groundbreaking idea about low-altitude ...
