Cover ENERGY STORAGE Solar and energy storage - A perfect match Besides grid stabilization and load leveling, storage systems can potentially provide back-up power to thousands of residential and commercial customers, especially when solar or wind is not available. Features MODULE/CELL ASSEMBLY & RELIABILITY Materials engineering enhances solar performance The manufacture of photovoltaic (PV) cells and modules mandates designed-in materials engineering to reduce development time, streamline production, and optimize performance. MODULE & CELL RELIABILITY A realistic accelerated testing methodology to evaluate PV module durability Short of having real time outdoor testing data for all the materials and combinations of interest to the modern PV marketplace, there is a realistic testing approach that is able to reduce the risk of potential premature failure. UNDERSTANDING EHS ISSUES Thermal oxidation and solar dryers Thermal oxidation contributes to a considerable reduction of potential condensation, which results in significantly minimized drying system maintenance expenses. MODULE ASSEMBLY Reducing cost/improving efficiency in solar modules Current module assembly methodologies based on solder processes, while effective for today's cell dimensions, are challenged by the move to thinner, larger solar cells. BACK SHEET LAMINATION Lamination - key to module reliability Approaches used to address lamination process bottlenecks include using larger area laminators, multiple parallel laminators, stack laminators (multiple lamination chambers in a vertical stack), and multi-stage laminators, in which the process steps are split into different processing units. BACK SHEET LAMINATION The challenges facing back sheet manufacturers The PV community realizes the limitations of current test methods and is working on a new IEC document that will address concerns. Last Rays Solar cell process costs and materials Current evaluation of the polysilicon availability shows it is in an oversupply situation for the next few years. However, research indicates that the polysilicon and wafer availability to solar and semiconductor manufacturers is tight.
