Double-sided silicon wafer solar glass

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.

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.

Does a variation of a wafer texture affect solar cell performance?

Here, we assumed that the variation of the additive will not drastically change the picture and will not require a complete re-optimization of the process. The focus of this work, however, is not to find the best additive but to correlate the wafer texture with solar cell performance.

Why do c-Si wafers have a high surface defect density?

Since the texture not only is crucial to enhance light trapping but also has a high impact on the surface defect density, electrical properties of the c-Si wafers, such as the lifetime of the minority charge carriers, are influenced as well.
