Determination of the collection diffusion length by electroluminescence imaging

Schinke, Carsten; Hinken, David; Bothe, Karsten; Ulzhöfer, Christian; Milsted, Ashley; Schmidt, Jan; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)

The electroluminescence emission of crystalline silicon solar cells at near-bandgap wavelengths is investigated. We show that the intensity of the emitted luminescence at near-bandgap wavelengths is directly proportional ...
Introducing pinhole magnification by selective etching: Application to poly-Si on ultra-thin silicon oxide films

Tetzlaff, Dominic; Dzinnik, Marvin; Krügener, Jan; Larionova, Yevgeniya; Reiter, Sina; Turcu, Mircea; Peibst, Robby; Höhne, Uwe; Kähler, Jan-Dirk; Wietler, Tobias F. (Amsterdam : Elsevier, 2017)

Carrier selective junctions formed by polycrystalline silicon (poly-Si) on ultra-thin silicon oxide films are currently in the spotlight of silicon photovoltaics. We develop a simple method using selective etching and ...
Luminescence emission from forward- and reverse-biased multicrystalline silicon solar cells

Bothe, Karsten; Ramspeck, K.; Hinken, D.; Schinke, Carsten; Schmidt, J.; Herlufsen, S.; Brendel, Rolf; Bauer, J.; Wagner, J.-M.; Zakharov, N.; Breitenstein, O. (College Park, MD : American Institute of Physics, 2009)

We study the emission of light from industrial multicrystalline silicon solar cells under forward and reverse biases. Camera-based luminescence imaging techniques and dark lock-in thermography are used to gain information ...
Parasitic Absorption in Polycrystalline Si-layers for Carrier-selective Front Junctions

Reiter, Sina; Koper, Nico; Reineke-Koch, Rolf; Larionova, Yevgeniya; Turcu, Mircea; Krügener, Jan; Tetzlaff, Dominic; Wietler, Tobias; Höhne, Uwe; Kähler, Jan-Dirk; Brendel, Rolf; Peibst, Robby (London : Elsevier Ltd., 2016)

We investigate the optical properties of n- and p-type polycrystalline silicon (poly-Si) layers. We determine the optical constants n and k of the complex refractive index of polycrystalline silicon by using variable-angle ...
Rear side dielectrics on interdigitating p+-(i)-n+ back-contact solar cells − hydrogenation vs. charge effects

Rienäcker, Michael; Larionova, Yevgeniya; Krügener, Jan; Wolter, Sascha; Brendel, Rolf; Peibst, Robby (Les Ulis : EDP Sciences, 2021)

Polysilicon-on-oxide (POLO) passivating contacts and interdigitated back-contact (IBC) cell technologies have recently attracted a lot of interest as candidates for the implementation in the next generation of solar cells. ...
Recombination Behavior of Photolithography-free Back Junction Back Contact Solar Cells with Carrier-selective Polysilicon on Oxide Junctions for Both Polarities

Rienäcker, Michael; Merkle, Agnes; Römer, Udo; Kohlenberg, Heike; Krügener, Jan; Brendel, Rolf; Peibst, Robby (London : Elsevier Ltd., 2016)

We report on ion-implanted, inkjet patterned back junction back contact silicon solar cells with POLysilicon on Oxide (POLO) junctions for both polarities – n+ doped BSF and p+ doped emitter. The recombination behavior is ...
Understanding the Light-induced Lifetime Degradation and Regeneration in Multicrystalline Silicon

Bredemeier, Dennis; Walter, Dominic; Herlufsen, Sandra; Schmidt, Jan (London : Elsevier Ltd., 2016)

In this contribution, we focus on improving the fundamental understanding of the carrier lifetime degradation and regeneration observed in block-cast multicrystalline silicon (mc-Si) wafers under illumination at elevated ...
