Photovoltaic Response of Silicon Wafers Treated in the K₂WO₄-Na₂WO₄-WO₃ Melt

Texturing silicon wafers is one way to increase the performance of solar cells. This work is the first to report on the surface modification of Si wafers by processing in polytungstate melts. Scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction analysis (XRD), the Brunauer–Emmett–Teller (BET) method, and photoelectrochemical measurements were used to elucidate the effect of texturing conditions in the Na 2 WO 4 —K...
