Nanotexturing enables perovskite/silicon tandem solar cells with 29.8% efficiency

Introducing nanotextured interfaces simultaneously increases the light-harvesting ability, optoelectronic properties and fabrication yield of perovskite/silicon tandem solar cells. In this way, the efficiency limit of conventional silicon solar cells is surpassed, paving the way to higher-performance photovoltaics.
