Do photovoltaic technologies need a renewed assessment?

Nature Reviews Materials 4, 269–285 (2019) Cite this article The remarkable development in photovoltaic (PV) technologies over the past 5 years calls for a renewed assessment of their performance and potential for future progress.

What are the most important PV materials?

Summary and outlook We have tried to give an up to date perspective of PV materials. The most important material has been and still is silicon. It dominates the present world market, particularly in its crystalline form but amorphous silicon is also of importance.

Is G A good material for photovoltaic cells?

In addition, G is one of the strongest materials on earth, with an elastic modulus close to 1 TPa, a tensile strength of 130 GPa and a breaking strength of ∼40 N/m [ 118, 119 ]. The combination of these exceptional properties make G an excellent candidate for application in photovoltaic cells.

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.

What are the different types of photovoltaic (PV) applications?

There are many Photovoltaic (PV) applications, including Building Integrated Photovoltaics (BIPV), buildings with weight limitations, buildings with curved roof surfaces, or other outdoor portable applications, where flexible or conformable PV products would be beneficial.

What elastomers are used in PV modules?

Recently various polyolefin (PO) elastomers and thermoplastic elastomers (POE and TPO, respectively) are being used for PV modules, especially glass-glass designs. Other materials such as ionomers, polyvinyl butyral (PVB) and silicones are also being considered and used sometimes.
