PROCESS AND APPARATUS FOR MEASURING THE CRYSTAL FRACTION OF CRYSTALLINE SILICON CASTED MONO WAFERS
摘要
<p>Provided are methods and apparatus for determining the crystal fraction of a casted-mono silicon wafer. A light source is directed at the wafer and the transmission or reflection is measured by a detector. An image of the wafer is generated by a processor and the crystal fraction is calculated from the generated image. The crystal fraction is correlated to the efficiency of the solar cell produced, allowing for the rejection of inferior wafers prior to processing.</p>
