coordinate variables x1, . . ., xn from subsequent interpretation of the model in ‘real’ terms (which can be, in particular, a visualization). The concept of multimedia types is exploited here. A special mapping giving each coordinate an interpretation has been proposed (for instance, ‘x’, ‘y’, ‘z’ types can correspond to Cartesian coordinates; ‘t’, to ‘dynamic’ coordinate representing continuo...

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:...
