The optical performance of random and periodic textured mono crystalline silicon surfaces for photovoltaic applications

EPJ Photovoltaics, 2022
Surface textures that result in high optical yields are crucial for high efficiency photovoltaic (PV) devices. In this work three different texturing approaches are presented that result in smooth concave structures devoid of sharp features.
