  • A Cross-Country Model for End-Use Specific Aggregated Household Load Profiles 
    Schlemminger, Marlon; Niepelt, Raphael; Brendel, Rolf (Basel : MDPI, 2021)
    End-use specific residential electricity load profiles are of interest for energy system modelling that requires future load curves or demand-side management. We present a model that is applicable across countries to predict ...
  • Flexible und robuste Wege zur Energiewende : Neue Transformationspfade zu einem nachhaltigen Energiesystem 
    Niepelt, Raphael; von Haaren, Christina; Breitner, Michael; Gronau, Sven; Brendel, Rolf; Hanke-Rauschenbach, Richard (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2022)

  • For none, one, or two polarities—How do POLO junctions fit best into industrial Si solar cells? 
    Peibst, Robby; Kruse, Christian; Schäfer, Sören; Mertens, Verena; Bordihn, Stefan; Dullweber, Thorsten; Haase, Felix; Hollemann, Christina; Lim, Bianca; Min, Byungsul; Niepelt, Raphael; Schulte‐Huxel, Henning; Brendel, Rolf (Chichester : Wiley, 2019-11-05)
    We present a systematic study on the benefit of the implementation of poly-Si on oxide (POLO) or related junctions into p-type industrial Si solar cells as compared with the benchmark of Passivated Emitter and Rear Cell ...
  • High-quality exfoliated crystalline silicon foils for solar cell applications 
    Niepelt, Raphael; Hensen, Jan; Knorr, Alwina; Steckenreiter, Verena; Kajari-Schröder, Sarah; Brendel, Rolf (Amsterdam : Elsevier, 2014)
    Kerfless wafering techniques offer a significant cost saving potential via the reduction of silicon consumption. In this paper, we examine thin single crystalline Si foils that were fabricated by a novel kerfless ...
  • Kerfless exfoliated thin crystalline Si wafers with Al metallization layers for solar cells 
    Niepelt, Raphael; Hensen, Jan; Steckenreiter, Verena; Brendel, Rolf; Kajari-Schröder, Sarah (Cambridge : Cambridge University Press, 2015)
    We report on a kerfless exfoliation approach to further reduce the costs of crystalline silicon photovoltaics making use of evaporated Al as a double functional layer. The Al serves as the stress inducing element to drive ...
  • Large-scale spatiotemporal calculation of photovoltaic capacity factors using ray tracing: A case study in urban environments 
    Bredemeier, Dennis; Schinke, Carsten; Niepelt, Raphael; Brendel, Rolf (Chichester : Wiley, 2023)
    Photovoltaics (PVs) on building facades, either building-integrated or building-attached, offer a large energy yield potential especially in densely populated urban areas. Targeting this potential requires the availability ...
  • Numerical modelling and validation of thermally-induced spalling 
    Berardone, Irene; Kajari-Schröder, Sarah; Niepelt, Raphael; Hensen, Jan; Steckenreiter, Verena; Paggi, Marco (London : Elsevier Ltd., 2015)
    In order to reduce the silicon consumption in the production of crystalline silicon solar cells, the improvement of sawing techniques or the use of a kerf-less process are possible solutions. This study focuses on a ...
  • Simulative Kurzstudie zum Einsatz von Wasserstofftechnologie in Niedersachsen 
    Peterssen, Florian; Schlemminger, Marlon; Niepelt, Raphael; Hanke-Rauschenbach, Richard; Brendel, Rolf (Hameln : Institut für Solarenergieforschung Hameln (ISFH), 2021-06-30)
    Grüne chemische Energieträger, die mit erneuerbar erzeugtem Strom hergestellt werden, sind ein wichtiger zukünftiger Baustein der Energiewende. Sie werden vor allem für Prozesse und Verbraucher, die nur schwer durch Strom ...
  • Thermomechanical Spalling of Epitaxially Grown Silicon from Porosified Substrates 
    Steckenreiter, Verena; Hensen, Jan; Knorr, Alwina; Niepelt, Raphael; Brendel, Rolf; Kajari-Schröder, Sarah (London : Elsevier Ltd., 2016)
    We combine two kerfless approaches to unite advantages of both processes: the epitaxial layer transfer based on porous silicon (PSI process) and the lift-off of a thin silicon layer from a substrate via controlled spalling ...
  • Thin crystalline macroporous silicon solar cells with ion implanted emitter 
    Ernst, Marco; Schulte-Huxel, Henning; Niepelt, Raphael; Kajari-Schröder, Sarah; Brendel, Rolf (Amsterdam : Elsevier, 2013)
    We separate a (34 ± 2) μm-thick macroporous Si layer from an n-type Si wafer by means of electrochemical etching. The porosity is p = (26.2 ± 2.4)%. We use ion implantation to selectively dope the outer surfaces of the ...
