Novel and stable materials for energy conversion

  • Branch of study: Economics of Energy and Electrical Engineering
  • Department: Department of Electrotechnology
    • Description:
      The work includes the preparation and characterization of materials for energy conversion. In particular, these are materials that serve either as an electrode or as a sunlight absorber in a battery or a solar cell. In the case of electrodes, the materials can be either metal oxides or organic molecules. In the case of absorber, we will start from hybrid organic-inorganic halide perovskite and we will look for new lead-free, fully inorganic alternatives, e.g. lithium thiospinels. The main technology used will be Pulsed Laser Deposition, sputtering and spin coating form a solution. The characterization methods will be the photoluminescence, ellipsometry, optical absorption, electrical measurements, as well as evaluation of material stability in time.

Technology of high efficient solar cell for operating at low illumination

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Electrotechnology
    • Description:
      One of the goals of the project is to develop a high-efficient solar cell working at lower illumination. The technology uses a very thin silicon wafer passivated by tunnel oxide, and the concept of selective contacts formed by transparent conductive oxides. The topic of theses will be focused on the effects of selected technological parameters of wet etching, sputtering, laser ablation deposition on the optoelectronic properties of the prepared structures. Several characterization methods will also developed, e.g. measuring the contact resistance by TLM, mapping lifetime by photoluminesence, I-V measurements under a solar simulator, etc. M.
