  3. Solar Cells Lecture 4: What is Different about Thin-Film Solar Cells?

    29 Aug 2011 | | Contributor(s):: Muhammad A. Alam

    Thin film solar cells promise acceptable efficiency at low cost. This tutorial examines the device physics of thin-film solar cells, which generally require a different type of analysis than crystalline solar cells.

  4. Solar Cells Lecture 5: Organic Photovoltaics

    29 Aug 2011 | | Contributor(s):: Muhammad A. Alam

    Organic solar cells make use of low-cost organic polymers forphotovoltaics. Although these solar cells may appear to be quitedifferent from solar cells made with conventional, inorganicsemiconductors (e.g. they make use of exciton generation rather than electron-hole generation) this...

  5. Spin Transport and Topological Insulators I

    29 Aug 2011 | | Contributor(s):: Supriyo Datta

    A major development of the last two decades, the physical and conceptual integration of what used to be two distinct unrelated fields, namely spintronics and magnetics.

  6. Thermal Transport Across Interfaces

    23 Aug 2011 | | Contributor(s):: Timothy S Fisher

    These lectures provide a theoretical development of the transport ofthermal energy by conduction in nanomaterials, in which materialinterfaces typically dominate transport. The physical nature of energytransport by two carriers: electrons and phonons--will be explored.

  7. Spin Transport and Topological Insulators II

    19 Aug 2011 | | Contributor(s):: Supriyo Datta

    A major development of the last two decades, the physical and conceptual integration of what used to be two distinct unrelated fields, namely spintronics and magnetics.
