Glass Cleaning

Poor transmission of sunlight through the top glass cover is one of the major hindrances in realizing better performance from a PV module. Adoption of appropriate cleaning technique might enhance glass transmissivity to a good extent. In the present study, the effect of manual cleaning with nylon sponge, microfiber cloth and nylon brush on optical and mechanical properties of PV glass have been investigated for several samples of borosilicate and soda lime glasses. Examination of transmittance of the samples using UV-VIS NIR scanning spectrophotometer confirmed enhanced transmissivity. Borosilicate glass exhibited better performance in terms of transmissivity as compared to soda lime glass. Cleaning with nylon sponge shows the highest transmittance of 91.98% for borosilicate glass at 630 nm wavelength and that of 91.094% with soda lime at 525 nm wavelength.

Laser beam cutting is a non-contact, production-flexible and highly productive technique that allows accurate profiling of a wide range of sheet materials. To these and further benefits, laser machining is increasingly being adopted by industry. This paper investigates the effect of material type, workpiece thickness, cutting speed and assistant gas pressure on cut quality for industrial-relevant applications using a CO2 laser. AlMg3 aluminum alloy, St37-2 low-carbon steel and AISI 304 stainless steel were selected to represent the most established materials in many industrial fields and gain insight into different processes (i.e., inert-assisted fusion cutting and oxygen cutting) and absorption behaviors with respect to CO2 laser wavelength. The aim was to enhance the understanding of the mechanisms through which laser cutting parameters and workpiece parameters interact in order to identify general criteria and well-optimized process parameters which guarantee the kerf quality. The quality of laser cut was analyzed in its basic terms: kerf geometry, surface roughness and cut edge quality. The experiments were performed by using a systematic experimental design approach based on Design of Experiments, and the results were validated via Analysis of Variance. Quality assessment was presented and discussed. The visual inspection of cut sections confirms good overall quality and limited presence of laser cut imperfections. The experimental investigation demonstrates that the different materials can be successfully processed within a wide range of the tested values. In addition, optimum cutting conditions which satisfy the straight requirement of the quality standard adopted are identified for each material. This study involves an analysis of both phenomenological and practical issues.

Cut Depth

An experimental investigation was conducted using a CO2 laser to cut fibrous insulation blankets for the Space Shuttle and high speed aircraft. This investigation was unique in identifying important factors for controlling the cut depth, thus, allowing the laser to be used for making partial cuts in a composite quilt. The investigation determined an algorithm for essential physical parameters used in automating the laser machining of these materials.

The Impact

This paper indicates the experiments of YAG laser cutting soda-lime glass with controlled fracture. The qualities of glass obtained by laser cutting and mechanical cutting are compared. The impact of laser power, scanning speed and spot size on the cutting quality is studied and the optimum laser parameters are given. Finally the experiments of laser cutting two-layer glasses, glass tube and laser cutting in curve paths are carried out. The results show that good cutting quality of glass can be acquired by YAG laser cutting.
