Ten Kate, O.M. (author), De Jong, M. (author), Hintzen, H.T. (author), Van der Kolk, E. (author)Solar cells of which the efficiency is not limited by the Shockley-Queisser limit can be obtained by integrating a luminescent spectral conversion layer into the cell structure. We have calculated the maximum efficiency of state-of-the-art c-Si, pc-Si, a-Si, CdTe, GaAs, CIS, CIGS, CGS, GaSb, and Ge solar cells with and without an integrated...journal article 2013

Van der Kolk, E. (author), Basun, S.A. (author), Imbusch, G.F. (author), Yen, W.M. (author)Electron delocalization processes of optically excited states of Ce3+ impurities in Lu2SiO5 were investigated by means of a temperature and spectrally resolved photoconductivity study. By monitoring separately the strength of the photocurrent resulting from excitation into each of the Ce3+?5d absorption bands, over a broad temperature region,...journal article 2003
