Effective passivation of crystalline silicon surfaces by ultrathin atomic-layer-deposited TiOx layers

Titova, V.; Veith-Wolf, B.; Startsev, D.; Schmidt, J. (London : Elsevier Ltd., 2017)

We characterize the surface passivation properties of ultrathin titanium oxide (TiOx) films deposited by atomic layer deposition (ALD) on crystalline silicon by means of carrier lifetime measurements. We compare different ...
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 ...
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 ...
