|2010 M: Thin film chalcogenide photovoltaic materials|
This symposium shall concentrate on chalcogenide photovoltaic materials such as CdM (M=S,Se,Te), CuMX2 (M=Al,In,Ga and X=S,Se,Te) and related ones such as Cu2ZnSnS4. The aspects treated in this symposium range from material growth and properties up to material application in devices. In connection with above chalcogenide compounds, relevant materials used in devices in conjunction, such as n- and p-type transparent conductive materials are treated as well.
Chalcogenide semiconductors are also considered as promising candidates for next generation photovoltaics in the form of tandem cells and nanostructured cells. Here the scientific aspects are among others sub-bandgap transparency, doping ability and nanoparticle stability.
Since the beginning of this century, Chalcogenide based solar cells have evolved from a development stage to a fast growing industry. Yet many material issues related to defects or interfaces are unresolved, where focus is both on characterization techniques and fundamental understanding. Although chalcogenide photovoltaic materials are already used in commercial products, their growth and thin film preparation remain a subject of vivid research. Low-cost preparation techniques as well as high-speed deposition are addressed in several laboratories in the world.
Because the emphasis is on Materials R&D, relevant to PV, rather than on PV technology, the symposium will complement rather than overlap with the various PV Solar Cell Specialist and Technology Conferences.
The symposium is part of the successful biannual series of E-MRS symposia (1999, 2000, 2002, 2004, 2006, 2008) on "Chalcogenide semiconductors for photovoltaics", complemented by MRS Spring Meeting ones on "II-VI Compound Semiconductor Photovoltaic Materials", in 2001, 2003, 2005, 2007, 2009. The symposium will be organized along similar lines, i.e., with ample time for both structured and free discussion sessions, centred on the main topics of the symposium. A satellite tutorial on specific topics of relevance for young scientists will be organized in connection with the symposium.
