Is polysilicon a bottleneck for solar PV?

Global capacity for manufacturing wafers and cells, which are key solar PV elements, and for assembling them into solar panels (also known as modules), exceeded demand by at least 100% at the end of 2021. By contrast, production of polysilicon, the key material for solar PV, is currently a bottleneck in an otherwise oversupplied supply chain.

Are solar PV supply chains cost-competitive?

Currently, the cost competitiveness of existing solar PV manufacturing is a key challenge to diversifying supply chains. China is the most cost-competitive location to manufacture all components of the solar PV supply chain. Costs in China are 10% lower than in India, 20% lower than in the United States, and 35% lower than in Europe.

How are photovoltaic absorbers made?

The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation. Laser scribing is used to pattern cell strips and to form an interconnect pathway between adjacent cells.

Should solar panels be built around low-carbon industrial clusters?

Building solar PV manufacturing around low-carbon industrial clusters can unlock the benefits of economies of scale. Solar panel manufacturers can also use their products to generate their own renewable electricity on site, thereby reducing both electricity bills and emissions.

What is Antora energy's new 2MW TPV factory?

Antora Energy's new 2 MW factory produces thermophotovoltaic cells with a heat-to-electricity conversion efficiency of more than 40%. These cells are based on III-V semiconductors and are intended for thermal storage applications.

How efficient is a thermophotovoltaic cell?

A thermophotovoltaic cell achieved an efficiency of 41.1% in an experiment. The group presented this achievement in the article "Thermophotovoltaic efficiency of 40%," published in Nature.
