Concentric-circle vacuum photo-thermal photoelectric conversion glass tube

Abstract

A concentric-circle vacuum photo-thermal photoelectric conversion glass tube comprises an outer glass tube, an inner glass tube, two layers of anti-reflection films, a photoelectric conversion layer, a photo-thermal conversion layer, a heat conduction layer, a sealing solder, a support, a getter and the like. The transparent photoelectric conversion layer in a vacuum chamber converts sunlight into electric energy. The photo-thermal conversion layer converts the sunlight transmitted through the photoelectric conversion layer into heat energy. The heat conduction layer rapidly transmits the heat. Therefore, photoelectric and photo-thermal comprehensive utilization can be completed. The getter is placed on a bottom of the glass tube. When the getter is heated, influence of the getter on the coating film can be reduced to be minimal. The sealing solder is finally sealed and is located on an edge of the vacuum glass. A normal of a sealing surface is parallel to an axis of a concentric circle tube and an electrode is guaranteed to be fixed completely. The structure of the glass tube of the invention is simple and reasonable. Production and manufacturing are easy. Cost is low. Photo-thermal and photoelectric conversion efficiency is high. The glass tube is easy to be widely used. The shape of the concentric-circle vacuum photo-thermal photoelectric conversion glass tube is similar with the shape of a common solar energy glass tube. During a transportation and storage process, various kinds of damages can be effectively avoided.
