A non-metallic additive for diamond-wire-sawn multi-crystalline silicon texturing
نویسندگان
چکیده
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 reduce reflectance morphology. Compared textured wafers without additive, this method uniformly distributed with pits whose size 0.5 μm×1 μm. And weighted average can be reduced from 33.32% 23.9% wavelength range 350–1100 nm, lowest 19.8% reached at 950 nm. shows promising application prospect.

Surface characteristics and damage distributions of diamond wire sawn wafers for silicon solar cells
This paper describes surface characteristics, in terms of its morphology, roughness and near-surface damage of Si wafers cut by diamond wire sawing (DWS) of Si ingots under different cutting conditions. Diamond wire sawn Si wafers exhibit nearly-periodic surface features of different spatial wavelengths, which correspond to kinematics of various movements during wafering, such as ingot feed, wi...
متن کاملCharacterization of the Diamond Wire Sawing Process for Monocrystalline Silicon by Raman Spectroscopy and SIREX Polarimetry
A detailed approach to evaluate the sub-surface damage of diamond wire-sawn monocrystalline silicon wafers relating to the sawing process is presented. Residual stresses, the presence of amorphous silicon and microcracks are considered and related to diamond wire velocity and cutting ability. In particular, the degree of amorphization of the wafer surface is analyzed, as it may affect the etchi...
متن کاملSoft-pad grinding of 300 mm wire-sawn silicon wafers: finite element analysis with designed experiments
Silicon wafers are the primary semiconductor substrates used to fabricate Integrated Circuits (ICs). Recently, the industry is making a transition from 200 to 300 mm wafers. To attain very flat 300 mm silicon wafers, grinding has been used to flatten the wire-sawn wafers. However, it is challenging for grinding to remove the waviness induced in wire sawing. To enhance the waviness removal abili...
متن کاملTexturing for Heterojunction Silicon Solar Cells
Heterojunction solar cells have potential for very high device voltages and currents, yet this relies on correct preparation of wafer surfaces prior to a-Si deposition. This paper investigates the preparation of wafer surfaces by NaOH texturing prior to amorphous silicon intrinsic layer deposition. It is found that with a CP etch or low temperature anneal after texturing, and with correct depos...
متن کاملDevelopment of Multi-wire Edm Slicing Method for Silicon Ingot
INSTRUCTIONS The diameter of silicon wafer becomes larger in order to increase the number of chips per one wafer. For such a larger diameter silicon ingot is mainly sliced by using multi-wire method, in which a long thin wire is used with slurry. In this method, several hundreds of wafers could be sliced at the same time. However there are still problems remained, such as large cracks, slurry t...
