Are new materials a technology risk for the photovoltaic cell and module industry?

This presents a technology risk for the industry. This report provides a global survey from IEA PVPS member countries of efforts being made to design new materials for photovoltaic cell and module applications.

What is cable-supported photovoltaic (PV)?

Cable-supported photovoltaic (PV) modules have been proposed to replace traditional beam-supported PV modules. The new system uses suspension cables to bear the loads of the PV modules and therefore has the characteristics of a long span, light weight, strong load capacity, and adaptability to complex terrains.

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.

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.

How to recycle solar cells from photovoltaic modules?
