Abstract
The present invention relates to a light absorbing layer (1a) for a photovoltaic device, comprising a plurality of grains (2) of a doped semiconducting material and a charge conductor (3) made of a charge conducting material in physical contact with the grains. The grains are partly covered with the charge conductor (3) so that a plurality of junctions (4) are formed between the grains and the charge conductor. The present invention also relates to a photovoltaic device comprising the light absorbing layer (1a).
