Title: Development of Optimal CZTS Device Structure: Cooperative Research and Development Final Report, CRADA Number CRD-12-476

Abstract

Suntricity Corporation and NREL will develop an optimal CZTS device structure. In this process absorber materials provided by Suntricity Corporation will be used for testing. For this purpose Suntricity Corporation will provide dried film precursors or ink precursors. NREL will process these into PV material and complete cells with buffer, window and contacts.

  • Opportunities for combining energy efficiency, demand response, and energy storage with PV are often missed, because the required knowledge and expertise for these different technologies exist in separate organizations or individuals. Furthermore, there is a lack of quantitative tools to optimize energy efficiency, demand response and energy storage with PV, especially for existing buildings. Our goal is to develop a modeling tool, BEopt-CA (Ex), with capabilities to facilitate identification and implementation of a balanced integration of energy efficiency (EE), demand response (DR), and energy storage (ES) with photovoltaics (PV) within the residential retrofit market. To achieve this goal, we willmore » adapt and extend an existing tool -- BEopt -- that is designed to identify optimal combinations of efficiency and PV in new home designs. In addition, we will develop multifamily residential modeling capabilities for use in California, to facilitate integration of distributed solar power into the grid in order to maximize its value to California ratepayers. The project is follow-on research that leverages previous California Solar Initiative RD&D investment in the BEopt software. BEopt facilitates finding the least cost combination of energy efficiency and renewables to support integrated DSM (iDSM) and Zero Net Energy (ZNE) in California residential buildings. However, BEopt is currently focused on modeling single-family houses and does not include satisfactory capabilities for modeling multifamily homes. The project brings BEopt's existing modeling and optimization capabilities to multifamily buildings, including duplexes, triplexes, townhouses, flats, and low-rise apartment buildings.« less
  • The possibility of a reflecting electrochromic device is very attractive, and the 'Buried Anode' architecture developed at NREL could yield such a device. The subject of this cooperative agreement will be the development and refinement of a Buried Anode device process. This development will require the active involvement of NREL and US e-Chromic personnel, and will require the use of NREL equipment as much as possible. When this effort is concluded, US e-Chromic will have enough information to construct a pilot production line, where further development can continue.
  • Through this Cooperative Research and Development Agreement, NREL and PrimeStar Solar will work together to scale up the NREL CdTe photovoltaic process from the laboratory to produce photovoltaic devices in a size that is commercially viable. The work in this phase will focus on the transference of NREL CdTe device fabrication techniques to PrimeStar Solar. NREL and PrimeStar Solar will engage in a series of technical exchange meetings and laboratory training sessions to transfer the knowledge of CdTe PV film growth from NREL to PrimeStar Solar. PrimeStar Solar will grow thin films on PrimeStar Solar equipment and interleave them withmore » NREL-grown films in an effort to develop a commercial scale process on PrimeStar Solar equipment. Select NREL film growth equipment will be upgraded either by PrimeStar Solar or at PrimeStar Solar's expense to increase equipment reliability and throughput.« less
  • This research extends thin film materials and processes relevant to the development and production of a next generation photovoltaic device.
  • Crystal Solar has a novel approach for producing low-cost, monocrystalline silicon wafers that are capable of yielding high-efficiency solar cells. The approach involves epitaxial growth of the substrate and a proprietary lift-off technology. Crystal Solar will send selected wafers and cells to NREL for characterization and analyses. NREL will apply a variety of techniques to help identify mechanism(s) that limit the cell efficiency and suggest suitable approaches for mitigation.
