Abstract

There is provided a multi junction photovoltaic device comprising a first sub-cell comprising a photoactive region comprising a layer of perovskite material, a second sub-cell comprising a photoactive silicon absorber. and an intermediate region disposed between and connecting the first sub-cell and the second sub-cell. The intermediate region comprises an interconnect layer, the interconnect layer comprising a two-phase material comprising elongate (i.e. filament like) silicon nanocrystals embedded in a silicon oxide matrix.
