Advanced polarization spectroscopy of luminescence emitted by solar cell

Peer-reviewed article not indexed in WoS or Scopus

Solar photovoltaics is already important renewable energy source in terms of globally installed capacity. We can so say that solar power is the most promising long-term, clean, renewable energy resource. Photovoltaic area needs advanced diagnostic and control methods of large crystal defects. Diagnostic methods based on image capturing, processing, and advanced analysis have numerous uses in solar cell research and process development and quality inspection. Luminescence defects detection methods of silicon solar cells are some of the most common inspection methods today. Those diagnostic methods of solar cells have still significant diagnostic potential. According to the excitation method of luminescence radiation from silicon solar cells we talk about electroluminescence or photoluminescence methods. The main idea of this paper deals about the new potential direction in to use one of those characteristics luminescence radiation for detection defects of solar cells. Advanced polarization spectroscopy of defects luminescence in solar cells may be used to high-guality characterization of solar cells. There were used standart the existing electroluminescence technology and extend it about known polarization spectroscopy to yield the polarized band-gap luminescence light by polysilicon defects in solar cells structure. The goal of research results is to establish polarization dependence of defects luminescence radiation in band-gap luminescence emission.
