Abstract We have developed a process diagnostics system for photovoltaic energy modules based on standard methods and practices already developed for LSI and MEMS technologies. This paper provides a description of methods used to ensure the conformation of solar cell modules to the rigors of high-quality manufacturing necessary for reliable photovoltaic energy production when exposed to long-term environmental use. We have verified the possibility of inspecting each solar cell and the module assembly in detail for several photovoltaic technologies, specifically monocrystalline Si, polycrystalline Si, and CuInxGa1-xSe2 An objective set of criteria for the quality of each module can be provided by this method for use in module selection by consumers. Moreover, the quality of conformance and reliability data can be used as feedback to the manufacturer to minimize the number of defects created during manufacturing process and ameliorate their effects.

AbstractWe report on the first use of optical low coherence reflectometry (OLCR) for Edge Defined Film-Fed Growth (EFG) silicon characterization. This OLCR sensor system has been used to measure horizontal profiles of silicon thickness and flatness to an accuracy of 1.5 Rim with the sensor head positioned 1 cm away from the silicon. The use of this noninvasive sensor for EFG silicon growth monitoring may lead to more efficient solar cell manufacturing processes.

Conversion efficiency of solar cell is strongly affected by quality of substrate and the quality of substrate is influenced by melt convection if the substrate crystal is grown by melt growth technique. Therefore, melt convection control techniques are important to produce a high quality single crystal. In this paper, we have proposed a high frequency magnetic field applied CZ method and investigated the effect of high frequency magnetic field on silicon melt convection. The result reveals that the high frequency magnetic fields affect the tendency of the melt convection: until certain intensity of the high frequency magnetic field, the melt convection is suppressed and above such intensity of the high frequency magnetic field, the melt convection intensity is enhanced. This result indicates that the melt convection can be controlled by the high frequency magnetic field and the high quality silicon single crystals will be grown by this method.
