6 FAQs about [Research on new micro-nanostructured silicon materials and their broad-spectrum high-efficiency solar cells]

What is a monolithic micro/nanostructured perovskite/silicon tandem solar cell?

Why are nanowire solar cells more efficient?

Similar to periodic nanowire array with a larger lattice constant, the improved efficiency of the nanowire solar cells can be explained by enhancement in field concentration and the excitation of localized resonance modes .

Can nanotechnology improve solar performance?

The efforts in this framework are still ongoing, and from a research perspective, the use of nanotechnologies for the enhanced performance of such solar systems in various configurations and a wide variety of methods is something probably addressed more than any other approach.

What is the best nanomaterial for a solar cell?

The most promising nanomaterial for a solar cell is perovskite and CNTs. Three main factors block PSCs’ commercial application: PCE, cost, and stability. CNTs can be used as transparent and conducting materials instead of ITO. The best way to improve PCE and PSC stability is using CNTs as interlayers and back electrodes in PSCs.

Can nanofluids improve PCE of solar cells?

CNTs could effectively improve the PCE of solar cells and the efficiency of PCMs, but the cost of CNTs is a big challenge. There are two methods to prepare nanofluids, and the main challenges of nanofluids application are stability, sedimentation, and high cost of production.
