"throughput 15,000 to 20,000 wafers per hour... laser equipment continually processes high speed under laser scanner... rotary screen printing... integrated diffusion process and thermal oxidization into one process... Wafers stacked on top of each other... increasing throughput by factor of 2.4... contact of electrodes silicon solar cell formed on both sides in inline furnaces... three times faster belt speed... increase throughput while not compromising the efficiency of the solar cells"
