Photovoltaic efficiency of monolithic PO-TSCs. Credit score: Nature Power (2024). DOI: 10.1038/s41560-024-01451-8 Multi-junction photo voltaic cells, photo voltaic cells comprised of many particular person semiconductor junctions stacked collectively, have the potential of outperforming single-junction photo voltaic cells each by way of effectivity and stability. In recent times, materials scientists and engineers have been making an
