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 PV modules regulated by the RCRA?

The federal Resource Conservation and Recovery Act (RCRA) is the only policy governing hazardous waste management in the US , and does not include specific requirements for PV modules. Several states have their own specific regulations.

Are photovoltaic panels regulated?

Following the revision of the Waste Electrical and Electronic Equipment (WEEE) directive in 2012, the collection, transportation, and treatment of photovoltaic panels have been subject to regulation in each individual member of the European Union (EU) since 2014 .

What causes corrosion in photovoltaic modules?

Corrosion poses a significant challenge for the performance of photovoltaic modules, which is primarily caused by moisture in its various forms: water vapour, dew, rain, snow, and ice. Approximately 19 % of observed degradation in PV modules is attributed to corrosion .

Are reusing PV modules a good idea?

Research indicates that reusing modules results in the highest revenue with minimal processing compared to extracting components or materials (Recycling) . In most cases, reusing PV modules in their current condition without repair is generally more feasible and cost-effective.

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.
