Within this work, the OPTOS formalism (Optical Properties of Textured Optical Sheets) was used to compare a honeycomb texture featuring a high aspect ratio with state of the art random pyramids and the isotexture. The honeycomb texture exhibits an increased absorbed photocurrent density of 2.3 mA/cm(2) before and 0.7 mA/cm(2) after encapsulation compared to the isotexture for a 180 mu m thick solar cell. The simulated absolute value of 42.3 mA/cm(2) after encapsulation is even superior to the random pyramid texture with 41.5 mA/cm(2). Furthermore, a simulation-based optical yield analysis reveals that the angular irradiance of three exemplary terrestrial locations plays a minor role for the relative performance between the textures compared to influence of encapsulation effects.enSolarzellen - Entwicklung und CharakterisierungPhotovoltaikSilicium-PhotovoltaikNeuartige Photovoltaik-TechnologienOberflächen: KonditionierungPassivierungLichteinfangPhotonenmanagement621697journal article
