The result is a surface populated with randomized square-based pyramids where the sides are formed by planes and the base is the plane. For instance, a typical texturing recipe which uses a KOH concentration of 1-2% (in comparison to a 30-40В % concentration in saw damage removal) at 70-80вЊ. To accomplish lower etch rates, either the process temperature can be lowered and/or the etchant concentration decreased. To increase the anisotropy of the process the etch rate needs to be low, i.e. The main difference between saw damage etching and texturing is the etch rate.

The results and the system proposed are useful in implementing laser light scattering instruments for on-line monitoring of solar cell manufacturing processes which produce surface roughness patterns. In addition to virtual simulation, an experimental study of surface roughness effect on laser light scattering from textured surfaces is described.

The paper provides effective solution by combining an I/O and 3D graphic simulator to validate PLC code for implementation into a physical system with examined kinematics in energy manufacturing.

The process is tested virtually using 3-D software simulation before they are used in a full-scale physical plant. The programming is akin to the traditional text based programming conducted with actual robots, as it is responsible for controlling I/O, time delays, and motions along with basics. This visual interface is integrated into the virtual environment, which is designed to model the logical and kinematic functions of the automated system. The paper presents the integration and implementation of automated processes, based on the sequence control specifications and requirement of the PLC (programmable logic controller) using 3-D simulation to create a virtual test environment. Texture has long been known as one of the critical surface parameters affecting solar cell efficiency. An automated system in conjunction with a novel optical laser metrology technique has been designed via 3-D virtual simulation to study textured silicon wafers used for solar cell manufacturing.
