6 FAQs about [Price of auxiliary materials for photovoltaic circuit boards]

What materials are used in PV modules?

While low iron float glass is the most common material used in PV modules, it is heavy, re-quires tempering for safety, and sometimes presents adhesion problems that can lead to de-lamination. Frontsheets also typically include anti-reflective and anti-soiling coatings.

What are the sections of a PV module?

Section 1 is an introduction. Section 2 presents the state of the art in PV module materials including the functional requirements of each component and the common materials typically used to meet these requirements. Section 3 discusses the motivations for applying new material solutions to PV modules.

Are antireflective and anti-soiling coatings suitable for PV modules?

The durability of the candidate materials still has to be tested within a test module und combined stresses in order to check its suitability. Antireflective (AR) coatings have been commonly used in PV modules since ~2005, and anti-soiling (AS) coatings have been explored for use in PV since ~2015.

What is a crystalline silicon PV module made of?

Both crystalline silicon PV modules and most thin film modules are manufactured with a front cover made from tempered soda lime silicate glass - the same material used in buildings as window glass.

What materials are used for PV module frontsheets?

The most common material used for PV module frontsheets is low iron (<120 ppm Fe) float glass. Functional coatings are added to the surfaces of the glass to increase light adsorption (anti-reflective coatings) and/or to reduce the accumulation of dirt and debris on the module in the field (anti-soiling coatings).

Why should we investigate new materials for PV modules?

There are several motivations for investigating new materials for PV modules. Reducing or replacing expensive materials is important for the overall economics of module production. For example, reducing the use of or replacing silver with copper or aluminum leads to a significant cost reduction for manufacturers.
