Effective surface passivation is crucial for improving the performance of crystalline silicon solar cells. Wang et al. develop a sulfurization strategy that reduces the interfacial states and induces a surface electrical field at the same time. The approach significantly enhances the hole selectivity and, thus, the performance of solar cells.
