Symposium V: Advanced Materials Processing for Scalable Solar-Cell Manufacturing II

Advanced Materials Processing for Scalable Solar-Cell Manufacturing II

In the quest to achieve large-scale (ca. 100s of GW to TW) deployment of solar energy systems, a significant technical and market hurdle is the development of low-cost, high-volume materials manufacturing processes.  Indeed, there is a strong push by the U. S. Department of Energy to achieve total installed system costs of ~$1/Wp, which necessarily implies module costs of less than $0.5/Wp!  To achieve this goal, there is a tremendous need for high-throughput materials processing and manufacturing, which would simultaneously lead to high-performance absorber materials and charge-transport interfaces with minimal defects.  These must also lead to solar converters that can achieve long-term reliability.  Process control is critical to achieving commercial success for multicomponent systems such as CIGS, as well as for single- or polycrystalline Si, amorphous Si, CdTe, III-V, dye-sensitized, polymer, earth-abundant sulfide/phosphide, and next-generation solar cells.  Nano-structures and nanomanufacturing approaches are beginning to transform the PV manufacturing landscape by enabling low-cost printed thin-film PV module manufacturing.

This symposium will establish a forum for a strong industry-academia interaction, which will explore materials processing challenges related to scalable solar cell technologies, as well as novel materials processing approaches with the potential to provide novel cost-effective manufacturing capabilities to the solar industry.  Key themes to be considered include the intersection of solar-module manufacturing and nanomanufacturing, as well as low-temperature roll-to-roll manufacturing for novel solar-module technologies.  Technologies that can enable very high-efficiency module concepts (> 20%) in a relatively low-cost fashion will also be consid-ered. Processes that enable new coatings and energy-conversion-enhancement schemes such as up/down converters and antireflective layers will be addressed.
