Solar Cells with SWCNTs and MWCNTs

The use of semiconductors in photovoltaics, or solar cells, allows them to transform light into energy. Because of its potential as eco-friendly and effective light-harvesting technologies, solar cells have been in the spotlight recently. Extensive and ongoing research has focused on the potential critical role of single-walled carbon nanotubes (SWNTs) in these devices. The most essential metric in comparing single-walled carbon nanotubes (SWNTs) with multi-walled carbon nanotubes (MWNTs) is their optical transmittance, which is different at low densities. As a result, SWNTs are known to perform better than MWNTs. The semiconducting properties of SWNT films allow them to serve as active or charge-transporting materials.
