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 encapsulant materials can be used for PV modules?
Various encapsulant materials can be considered. Polyvinyl butyral (PVB) has been used for a long time for glass–glass PV modules, particularly for thin-film modules.
Are early PV modules encapsulated with silicone?
Photovoltaics International Early PV modules were often encapsulated with silicone, and have demonstrated outstanding stability in the field, with degradation rates over 20 to 30 years that are much lower than the typical degradation rates for EVA-encapsulated modules [3–5].
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.
