Abstract

This paper presents the technology optimization and the characterisation of an improved semitransparent solar cell structure that can be used for building integrated applications. Through-holes can be etched using ammonium persulfate doped 5 wt.% tetramethylammonium hydroxide (TMAH) solution that ensures a stable 1.52 μm/min etching rate maintained over the entire process. Diluted TMAH surface texturing combined with RF sputtered silicon nitride reduces the average surface reflectance to 2.50%. The efficiency of the anisotropically etched test structure device is 9% including grid contact and silicon through-hole areas, the reached transparency is 6.7%.
