The U.S. Photovoltaic Manufacturing Consortium (PVMC), together with the U.S. Department of Energy’s SunShot Initiative, organized the first PVMC Thought Leadership Forum, a gathering of solar executives and thought leaders focused on Applying Moonshot Thinking to the Commercial & Industrial Solar Market. The event took place July 15, 2015, in San Francisco, CA. The focus of the Forum was twofold: first, to discuss common challenges and collaborative approaches to tackle market hurdles; secondly, in the spirit of SunShot, ask the question, “how can moonshot thinking expand the set of solutions and accelerate the entire solar industry?” Discussions coalesced around five themes:
1. Moonshot Thinking & Solar Innovation
2. Increasing the Size of the “Available” C&I Market
3. Streamlining the Interconnection & Permitting Process
4. Streamlining the Customer Acquisition Process

U.S. PVMC BOS working group meeting. SEMATECH (ISMI) programs are presented to establish types of information shared by members participating in SEMATECH working groups, Councils and Forums. Member share templates for upcoming benchmark meeting on module and power electronics test, certification and standards are proposed.
The University of Toledo, Professor of Physics and NEG Chair in Silicate and Materials Science Dr. Robert Collins will provide an online technical presentation on the use of spectroscopic ellipsometry (SE) for thin film photovoltaics (PV), from the R&D level to the manufacturing scale. Real-time SE can provide insight into the optical, electronic property evolution, dielectric function of thin films during film fabrication. Mapping SE can be used to evaluate the uniformity of thickness and other layer properties in full scale completed modules and PV panels during manufacturing. Regardless of the scale at which you work with PV, please join us in listening to Dr. Collins explain how SE is of value to the PV industry as a whole, from laboratory R&D to commercial manufacturing.

This workshop will be an exercise to list and rank the challenges associated with implementing advanced photovoltaic module and power electronic designs. U.S. PVMC Balance of Systems programs will be developed that address the industry challenges identified and ranked as an output of this workshop.
With silicon feedstock and wafer costs making up as much as 61% of the cost of a final PV module, the crystalline silicon (c-Si) PV industry has investigated ways to lower cost in order to achieve cost competitiveness. In addition, thinner Si wafers together with kerfless wafering methods and c-Si recycling are of considerable interest in an effort to increase the utilization efficiency of polysilicon. There is still a limitation in the fundamental understanding of how the lower quality material and thinner/kerfless wafers ultimately affect efficiency and yield when manufacturing c-Si solar cells and modules.
Dr. Pradeep Haldar, CNSE Vice President for Clean Energy, will be speaking on the topic of Manufacturer Responses – Outlook for 2012/2013 from the Nexus of the Supply Chain.
The primary goals of the meeting were for the c-Si U.S. PVMC to formally introduce itself to the standards development organizations (SDO) and standards affiliated organizations (SAO), and then to identify the most effective ways for the c-Si U.S. PVMC to interact with these organizations.
