2D sb2s3 periodic structure induced absorption enhancement — •Wei Wang, Patrick Pfeiffer, and Lukas Schmidt-Mende — Konstanz University

Sb2S3 is a promising candidate for solar cell absorbers due to its high absorption coefficient, suitable band gap and earth-abundant constituents. Here we present the fabrication of 2D Sb2S3 structures by direct laser interference method and direct electron beam lithography method. The periodic structure induced absorption enhancement can be observed by UV-VIS absorption spectrum and verified by finite difference time domain (FDTD) simulation.
