Executive Director Of TechnologyAlion Aug 2011 - Aug 2012Richmond, CaAs head of the Technology Steering Committee, defined roadmap to achieve Alion’s module efficiency goals and cost targets (less than 0.5 $/W capex and product cost), responsible for modeling and understanding of device physics and materials properties. Led process transfer from lab to pilot as well as planning, scheduling and process development of the pilot line. Team leader of a cross-functional team comprised of technology, engineering and operations experts• Achieved all milestones set by the board of directors, on schedule and below budget• Key technical contributor: Demonstrated over 12% devices in R&D using Alion’s printed CdTe ink technology Successfully ramped up pilot line and achieved over 10% devices within 3 months of start of production• Mentored engineers to better design experiments (DOE, SRM) and analyze experimental results• Participated in the feasibility study of a 150 MW production line. Involved in budgeting, process transfer methodology and validation of the final product

Sr. Director Of EngineeringNanosolar Aug 2008 - Sep 2010Luckenwale, GermanyManaged module engineering and reliability team (12 engineers). Responsible for process development, manufacturing engineering and reliability of the module assembly. Recruited and mentored engineers in six sigma methodologies. Compared outdoor field data to indoor accelerated reliability tests (using SQL, JMP and PV Syst) to project long term module performance. Managed equipment vendor interactions on cost and delivery schedule. • Decreased module takt time. Demonstrated potential to achieve less than 20s/module takt time• Led the implementation of six sigma methodologies (SPC, FMEA, DOE)• Established an on-going reliability program at the module level; achieved TUV certification • Successful ramp-up of production tool, including step-and-repeat and pick-and-place operations• Built first commercial size prototypes

Director Of Device EngineeringNanosolar Mar 2007 - Jul 2008San Jose, CaManaged the pilot development team comprised of process engineers, equipment engineers, technicians and operators. Expanded the original team of 8 to over 20 people. Mentored engineers in process development and device physics. This team was very successful in achieving all milestones put forward by the executive management team and in having all production tools specified and ordered on schedule.• Delivery of key milestones, on-time and in-budget, as defined to the board of directors by the executive management team.• Developed roll-to-roll (R2R) processes on Al foil using NS proprietary ink technology to form CIGS solar cells• Led effort to develop in-line metrology in order to have direct feedback on the quality of the different layers being deposited• Managed tool design and vendor interaction going from pilot line (20 cm wide web) tooling to manufacturing scale (75cm wide) tooling. Equipment developed included a R2R slot die coater, in-line furnaces, R2R sputter coaters and a novel, in-line CdS deposition tool• Key technology contributor for a 300M$ round in VC fundraising
-
Solar Cell EngineerNanosolar Sep 2004 - Mar 2007Palo Alto, CaDeveloped a fast RTP process using NS proprietary ink technology on Al substrate. Optimized all process steps related to making a CIGS solar cell (PVD for TCO and Metal, CBD, RTP). Combined electro-optical measurements and device modeling to better understand losses mechanisms and improve device performance• World class CIGS conversion efficiencies achieved on glass (> 14%) and on Al foil (> 11%) using printed precursors• Key technology contributor for a 75M$ round in VC fundraising

Research AssistantUniversity Of Toledo Jan 2001 - Aug 2004The purpose of my research was to better understand CdS/CdTe solar cells.My work involved: depostion of the TCO, CdS, CdTe and metal layer characterization of the individual layer (SEM, XRD) as well as the finished device (IV measurement, CV, QE)During this work, I also had the chance to work with Pilkington on characterization of TCO deposited by APCVD, as well as with First Solar on CdS/CdTe solar cells and modules.I also co-invented a method using the photovoltaic effect to mitigate the effect of lateral non-uniformities on device performance
