The Australian Centre for Advanced Photovoltaics (ACAP) co-ordinates the activities of the Australian partners in the Australia-US Institute for Advanced Photovoltaics (AUSIAPV), supported by the Australian Renewable Energy Agency, to develop the next generations of photovoltaic technology and to provide a pipeline of opportunities for performance increase and cost reduction. The Australian partners in ACAP are UNSW, ANU, University of Melbourne, Monash University, University of Queensland and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) with industrial partners Suntech R&D Australia (now Wuxi Suntech), Trina Solar, Bluescope Steel and BT Imaging. AUSIAPV links ACAP with US-based partners, specifically the NSF/DOE Energy Research Center for Quantum Energy and Sustainable Technologies (QESST), the National Renewable Energy Laboratory, Sandia National Laboratories, Lawrence Berkeley National Laboratories, Stanford University, Georgia Institute of Technology and University of California Santa Barbara. These national and international research collaborations provide a pathway for highly visible, structured photovoltaic research collaboration between Australian and US researchers, institutes and agencies with significant joint programs based on the clear synergies between the participating organizations. The research program is organised under five collaborative Program Packages (PP1-PP5). PP1 deals with silicon wafer-based cells, focussing on three main areas: cells made from solar grade silicon, rear contact and silicon-based tandem cells. Program Package 2 (PP2) involves research into a range of organic solar cells, organic/inorganic hybrid cells, "earth abundant" thin-film materials, including Si and CZTS, and more futuristic "third generation" approaches, with the overall goal of demonstrating efficiency above 15% during the program for cells of above 1cm2 area and of demonstrating the feasibility of costs below the US SunShot targets. PP3, concerned with optics and characterisation, targets experimental demonstration that theoretical conversion limits can be increased by the use of structures that have a high local density of optical states, with particular emphasis on thin film organic and inorganic solar cells. PP4, manufacturing issues, will deliver a substantiated methodology for assessing manufacturing costs of the different technologies under investigation by the ACAP/AUSIAPV partnership. The overall cost target is to exceed the SunShot targets, for one or more of the technologies, in at least one major SunShot targeted application, as deduced by a substantiated costing methodology. PP5 involves education, training and outreach. ACAP/AUSIAPV began in February 2013 and will have an eight-year life. National and international partnerships have been and are being formed and significant results have been generated already. The main research topics, results and plans for the future will be presented.
