What is a double sided battery?

With the development of photovoltaic power generation industry, double-sided batteries have developed rapidly. At present, most double-sided battery modules in the market are packaged with double glass, and a few are packaged with transparent backsheet.

What is a double glass c-Si PV module?

Recently several double-glass (also called glass–glass or dual-glass modules) c-Si PV modules have been launched on the market, many of them by major PV manufacturers. These modules use a sheet of tempered glass at the rear of the module instead of the conventional polymer-based backsheet. There are several reasons why this structure is appealing.

What is the electrical performance of BYD double-glass modules?

The electrical performance of the BYD double-glass modules was as expected for multicrystalline cells, with power bins ranging from 245W to 265W for 60-cell modules, and from 295W to 315W for 72-cell modules. The modules were subjected to numerous accelerated ageing tests.

Are double-glass PV modules durable?

Double-glass PV modules are emerging as a technology which can deliver excellent performance and excellent durability at a competitive cost. In this paper a glass–glass module technology that uses liquid silicone encapsulation is described. The combination of the glass–glass structure and silicone is shown to lead to exceptional durability.

What is the market share of double sided battery modules in 2022?

According to reliable market research data, by the end of 2022, the market share of double-sided battery modules will exceed 90%. At the same time, the market share of transparent back sheet is relatively small, and double glass components will become the mainstream of the component market.
