Diamond-wire-sawn (DWS) technology has been widely used in the photovoltaic industry. When using HF/HNO 3 /H 2 O acid etching solution for texturing of DWS multi-crystalline silicon(mc-Si), aid additive is required to improve reactivity mc-Si surface solution. It also needs enhance nucleation and uniform growth surface. This paper proposes a non-metallic texturing. Sodium polyacrylate added red...

Texturing silicon wafers is one way to increase the performance of solar cells. This work first report on surface modification Si by processing in polytungstate melts. Scanning electron microscopy (SEM), atomic force (AFM), X-ray diffraction analysis (XRD), Brunauer–Emmett–Teller (BET) method, and photoelectrochemical measurements were used elucidate effect texturing conditions Na 2 WO 4 —K (1:...

Enhanced pyroelectric response is achieved via domain engineering from [001] grain-oriented, tetragonal-phase, lead-free 0.2(2/3K0.5Bi0.5TiO3-1/3BaTiO3)-0.8Na0.5Bi0.5TiO3 (KBT-BT-NBT) ceramics prepared by a templated grain growth method. The crystallographic orientation leads to large polarization in tetragonal symmetry; therefore, texturing along this direction employed enhance the pyroelectri...
