    Solar Cell Manufacturing Facility Intern Report.
    Introduction.
    As an intern at a solar cell manufacturing facility, I gained valuable experience in the production of photovoltaic cells. My responsibilities included:
    Assisting with the design and setup of the screen printing process.
    Monitoring and optimizing the printing process to ensure quality and efficiency.
    Troubleshooting and resolving issues that arose during production.
    Screen Printing Process.
    The screen printing process is a crucial step in the manufacture of solar cells. It involves tr
ansferring a pattern of conductive ink onto a silicon wafer. The following steps are involved:
    1. Preparation: The silicon wafer is cleaned and coated with a photosensitive emulsion.
xposed    2. Exposure: A mask is placed over the wafer, and UV light is used to expose the emulsion through the mask. This creates a hardened pattern on the wafer.
    3. Development: The wafer is washed with a solvent to remove the unexposed emulsion, leaving behind the conductive ink pattern.
    4. Drying: The wafer is dried to remove any remaining solvent.
    Monitoring and Optimization.
    During the internship, I monitored the screen printing process to ensure it produced high-quality solar cells. I checked parameters such as:
    Ink viscosity.
    Screen tension.
    Printing pressure.
    Drying temperature.
    By adjusting these parameters, I optimized the printing process to improve cell efficiency and reduce defects.
    Troubleshooting.
    Occasionally, issues arose during the printing process. I was responsible for troubleshooting and resolving these issues. Common problems included:
    Smudging: The ink spread beyond the desired pattern.
