Analysis of local Al-doped back surface fields for high efficiency screen-printed solar cells

Gatz, Sebastian; Bothe, Karsten; Müller, Jens; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)

In this paper, we investigate the surface recombination of local screen-printed aluminum contacts applied to rear passivated solar cells. We measure the surface recombination velocity by microwave-detected photoconductance ...
Comparison of the thermal stability of single Al2O3 layers and Al2O3/SiNx stacks for the surface passiviation of silicon

Veith, Boris; Werner, Florian; Zielke, Dimitri; Brendel, Rolf; Schmidt, Jan (Amsterdam : Elsevier BV, 2011)

We measure surface recombination velocities (SRVs) below 10 cm/s on low-resistivity (1.4 Ωcm) p-type crystalline silicon wafers passivated with plasma-assisted and thermal atomic layer deposited (ALD) aluminium oxide (Al2O3) ...
Fundamental consideration of junction formation strategies for phosphorus-doped emitters with J0e < 10 fA/cm2

Min, Byungsul; Krügener, Jan; Müller, Matthias; Bothe, Karsten; Brendel, Rolf (London : Elsevier Ltd., 2017)

This work shows the potential of further optimization of phosphorus-doped emitters in p-type silicon solar cells. We investigate the impact of different combinations of phosphorus doping profiles and surface passivation ...
High-rate atomic layer deposition of Al2O3 for the surface passivation of Si solar cells

Werner, Florian; Stals, Walter; Görtzen, Roger; Veith, Boris; Brendel, Rolf; Schmidt, Jan (Amsterdam : Elsevier BV, 2011)

High-rate spatial atomic layer deposition (ALD) enables an industrially relevant deposition of high-quality aluminum oxide (Al2O3) films for the surface passivation of silicon solar cells. We demonstrate a homogeneous ...
Implementation of full-area-deposited electron-selective TiOx layers into silicon solar cells

Titova, Valeriya; Schmidt, Jan (College Park, MD : American Institute of Physics, 2018)

We examine two different silicon solar cell designs featuring full-area electron-selective contacts based on ultrathin (2-3 nm) titanium oxide (TiOx) films deposited by atomic layer deposition. The first cell design applies ...
Simultaneous Contacting and Interconnection of Passivated Emitter and Rear Solar Cells

Schulte-Huxel, Henning; Petermann, Jan-Hendrik; Blankemeyer, Susanne; Steckenreiter, Verena; Kajari-Schröder, Sarah; Brendel, Rolf (London : Elsevier Ltd., 2016)

The back end process of passivated emitter and rear cells (PERC) consists of at least one laser process and three screen-printing steps followed by the stringing and tabbing of the cells. To reduce the number of steps we ...
