6 SiSoC Advisory Board SiSoC Decision Making Entity Formulates By-Laws Suggests Research Topics Votes to Select New R&D Projects Votes on New Industry and University Membership Nominations

7 SiSoC Research Topics Silicon Feedstock Silicon Crystallization Defects and Impurities: Gettering Passivation Mechanical Properties: Wafer Breakage Process Modeling and Simulation Device Design and Fabrication Advanced Characterization Module Technology

8 Funding/Communication/ Management Funding Annual industry member fees for research (~$600k US) NSF provides funds for operations support (~$140k US) Communication Website maintained by NCSU (password protected) Flyer available online (http://sisoc.biz) Project Selection and Management Two year research projects at universities Semi-annual meetings and progress reports Strong industry mentor-university interactions

9 Project Selection and Management Competitive Annual Project Selection Members provide a list of R & D topics of interest Universities submit 3-page project proposals Members vote to select projects and allocate funds In 2010, 8 projects were selected out of 10 proposals (5 fully funded and 3 partially funded) Project Management Two-year duration with competitive renewal option Progress reports during semi-annual meetings Strong industrial mentor-university interactions

10 Membership Levels and Fees Annual SiSoC membership fees paid by Industry and Agency members varies according to membership type: o Full Member: Fee $50,000 – 50 project selection pts. 2 votes on IAB issues, full patent/IP options o Associate Member: Fee $25,000 – 25 project selection pts. 1 vote on IAB issues, full patent/IP options o Observer Member: Fee $10,000 – no voting/no IP options NSF provides annual university operations support : o $80,000 – Primary Site (NC State U) o $50,000 – Partner Site (Ga Tech)

11 Examples of Completed and Ongoing Projects: I Mechanical Properties of Mono- and Multi-crystalline Silicon: Correlation with Impurities and Defects Gettering and Passivation of Defects in Low-Cost c-Si Materials Microscopic Studies of Recombination Centers, Passivation, and Hydrogenation Analysis of the Stress State in Thin Silicon Wafers Due to Handling Fundamental Understanding of a Boron Emitter and Back Surface Field Influence of Local Residual Stresses on Mechanical Properties and Crack Initiation/Propagation of Silicon PV Wafers Impact of Light Element Impurities (O, C, N) on the Structure and Electrical Behavior of Photovoltaic Crystalline Silicon

12 Implementation of Optimized Gettering and Passivation Strategies for Multicrystalline Silicon Solar Cells with Focus on Grain Size Dependence and Advanced Features Understanding and Development of Dielectrics for Backside Passivation of Low Cost, High Efficiency Silicon Solar Cells Analysis of the Effects of Wafer Slicing on the Mechanical Integrity of Silicon Wafers Conductive Antireflection Coatings for Si Solar Cells Impact of Oxygen, Carbon and Nitrogen on the Mechanical Properties and Crack Initiation/Propagation in Silicon PV Wafers Light Impurities and Transition Metals in Si Solar-Cell Materials Technology Computer Aided Design Tools for Silicon Solar Cells Examples of Completed and Ongoing Projects: II
