  • The 2020 photovoltaic technologies roadmap 
    Wilson, Gregory M.; Al-Jassim, Mowafak; Metzger, Wyatt K.; Glunz, Stefan W.; Verlinden, Pierre; Xiong, Gang; Mansfield, Lorelle M.; Stanbery, Billy J.; Zhu, Kai; Yan, Yanfa; Berry, Joseph J.; Ptak, Aaron J.; Dimroth, Frank; Kayes, Brendan M.; Tamboli, Adele C.; Peibst, Robby; Catchpole, Kylie; Reese, Matthew O.; Klinga, Christopher S.; Denholm, Paul; Morjaria, Mahesh; Deceglie, Michael G.; Freeman, Janine M.; Mikofski, Mark A.; Jordan, Dirk C.; TamizhMani, Govindasamy; Sulas-Kern, Dana B. (Bristol : IOP Publ., 2020)
    Over the past decade, the global cumulative installed photovoltaic (PV) capacity has grown exponentially, reaching 591 GW in 2019. Rapid progress was driven in large part by improvements in solar cell and module efficiencies, ...
  • Carrier lifetime instabilities in the bulk and at the surfaces of crystalline silicon solar cells triggered by fast-firing processes 
    Winter, Michael (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2024)
    Carrier lifetime instabilities in crystalline silicon solar cells under illumination affect the long-term stability of photovoltaic modules in view of the steadily increasing conversion efficiency of the solar cells used ...
  • Characterization and loss analyses of passivated emitter and rear cells 
    Kruse, Christian Nikolaus (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    This work presents characterization methods and simulation-based loss analyses for passivated emitter and rear (PERC) solar cells. Furthermore, it discusses possible ways of introducing poly-Si on thin inter-facial oxides ...
  • Characterization of multiterminal tandem photovoltaic devices and their subcell coupling 
    Geisz, John F.; McMahon, William E.; Buencuerpo, Jeronimo; Young, Michelle S.; Rienäcker, Michael; Tamboli, Adele C.; Warren, Emily L. (Maryland Heights, MO : Cell Press, 2021)
    Three-terminal (3T) and four-terminal (4T) tandem photovoltaic (PV) devices using various materials have been increasingly reported in the literature, but measurement standards are lacking. Here, multiterminal devices ...
  • Hierarchical Etching for Improved Optical Front-side Properties of Monocrystalline Si Solar Cells 
    Heinemeyer, Frank; Steckenreiter, Verena; Kiefer, Fabian; Peibst, Robby (London : Elsevier Ltd., 2015)
    We investigate a hierarchical surface structuring process to reduce the optical reflectance of monocrystalline Si solar cells to below the reflectance of state-of-the-art alkaline texturing. First, alkaline texturing is ...
  • Improved surface passivation and reduced parasitic absorption in PEDOT:PSS/c-Si heterojunction solar cells through the admixture of sorbitol 
    Halbich, Marc-Uwe; Zielke, Dimitri; Gogolin, Ralf; Sauer-Stieglitz, Rüdiger; Lövenich, Wilfried; Schmidt, Jan (London : Nature Publishing Group, 2019)
    We examine the impact of sorbitol admixture to the hole-conduction polymer PEDOT:PSS [poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)] on the characteristics of PEDOT:PSS/crystalline silicon heterojunction solar ...
  • Improved understanding of boron-oxygen-related carrier lifetime degradation and regeneration in crystalline silicon solar cells 
    Helmich, Lailah (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    This thesis examines carrier lifetime instabilities in oxygen-rich boron-doped p-type Czochralski-grown silicon (Cz-Si) with the focus on the permanent deactivation of the boron-oxygen (BO)-related defect center leading ...
  • Organic-silicon Solar Cells Exceeding 20% Efficiency 
    Zielke, Dimitri; Niehaves, Claudia; Lövenich, Wilfried; Elschner, Andreas; Hörteis, Matthias; Schmidt, Jan (Amsterdam : Elsevier, 2015)
    Aftera briefreview of therecent evolvement oforganic-silicon heterojunction solar cells,we present here our latest measurements of the saturation current densities (J0) and contact resistances (RC) of crystalline silicon ...
  • Separating the two polarities of the POLO contacts of an 26.1%-efficient IBC solar cell 
    Hollemann, C.; Haase, F.; Rienäcker, M.; Barnscheidt, V.; Krügener, J.; Folchert, N.; Brendel, R.; Richter, S.; Großer, S.; Sauter, E.; Hübner, J.; Oestreich, Michael; Peibst, R. (Berlin : Springer Nature, 2020)
    By applying an interdigitated back contacted solar cell concept with poly-Si on oxide passivating contacts an efficiency of 26.1% was achieved recently. In this paper the impact of the implemented initially intrinsic poly-Si ...
  • Tailoring the Photoelectrochemical Activity of TiO2 Electrodes by Multilayer Screen-Printing 
    Günnemann, Carsten; Curti, Mariano; Eckert, J. Gerrit; Schneider, Jenny; Bahnemann, Detlef W. (Weinheim : WILEY-VCH Verlag, 2019)
    Screen‐printing is a commonly used method for the preparation of photoelectrodes. Although previous studies have explored the effect of the number of printed layers on the efficiency of dye‐sensitized solar cells, its ...
