  , Organic Solar Cells (OSCs)

   - Working Principle of Solar Cells
    Solar cell operation is based on the photovoltaic effect. First, Active layer absorbs the light and charge carriers are
  generated. Generated charges are separated and then, collect the carriers at the electrodes to use to electrical energy.

   - Applications of Organic Solar cells

   - Organic Solar Cells
    Advantages: low cost, large area production, light weight and flexible organic solar cells
  Research interests: interfacial engineering, using plasmonic effect and tandem structure for high efficiency organic
  solar cells, fabricate transparent electrode

   - Quantum Dot Solar Cells
    Advantages: low cost, energy bandgap tunable, large potential of efficiency improvement
  Research interests: high efficiency QD solar cell fabrication by employing interfacial engineering, structure
  modification, etc.

   - Perovskite Solar Cells
    Advantages: High absorption coefficient enables perovskite film absorb almost every visible light. Long
  electron and hole diffusion length allow us to fabricate simple and high performance photovoltaics.
  Research interests: Interface engineering for improving charge collection to each electrode. Morphology
  control to enhance perovskite film quality.
