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 ...
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 ...
Minority carrier lifetime in silicon photovoltaics: The effect of oxygen precipitation

Murphy, J.D.; McGuire, R.E.; Bothe, K.; Voronkov, V.V.; Falster, R.J. (London : Elsevier Ltd., 2014)

Single-crystal Czochralski silicon used for photovoltaics is typically supersaturated with interstitial oxygen at temperatures just below the melting point. Oxide precipitates therefore can form during ingot cooling and ...
