AI Technical Summary

Technical Problem

Existing cadmium telluride BIPV sandwich hollow products lack back-connection junction boxes, which means that direct back-connection is required when side connection is inconvenient, resulting in high energy consumption and sacrificing the sound insulation, heat insulation and thermal insulation effects of hollow products.

Method used

A cadmium telluride hollow power generation glass for back-connected junction boxes is designed. A hollow cavity layer is formed by setting a sealing ring and sealant between the outer and inner encapsulation glass layers and connecting it to the junction box at the round hole to ensure airtightness. At the same time, ice blue tempered homogeneous glass, Low-e coating and PVB film are used to improve durability and heat insulation performance.

Benefits of technology

This technology effectively combines back-connected cadmium telluride sandwich monolayer products with insulated glass products, retaining sound insulation, heat insulation and thermal insulation effects, while improving the durability and safety of the device and reducing energy consumption.

Abstract

The utility model belongs to the technical field of cadmium telluride BIPV (building integrated photovoltaics), and particularly relates to cadmium telluride hollow power generation glass for back connection of a junction box, which comprises outer layer packaging glass I, a cadmium telluride power generation chip is adhered to one side of the outer layer packaging glass I, and inner layer packaging glass is adhered to one side, far away from the outer layer packaging glass I, of the cadmium telluride power generation chip. A sealing ring and a sealant are used for filling, so that the connection of the sealing ring, the inner-layer packaging glass and the outer-layer packaging glass II at the round hole is kept sealed, a hollow cavity layer is kept sealed, and positive and negative electrodes on two side edges of one side surface, close to the inner-layer packaging glass, of the cadmium telluride power generation chip are gathered towards the round hole by attaching conductive adhesive tapes. And then wiring is carried out through the center of the sealing ring and the junction box, so that the back-connected cadmium telluride interlayer single-piece product can be combined with a glass hollow product, and the effects of sound insulation, heat preservation and heat insulation of the glass hollow product can be kept while the cadmium telluride interlayer single-piece product is back-connected with the junction box.
