A working electrode for a photovoltaic device, comprising:
- a light absorbing layer;
- and
- a conductive layer arranged in electrical contact with the light absorbing layer,
- wherein the light absorbing layer comprises a light absorbing photovoltaic material consisting of a plurality of dye molecules,
- wherein the light absorbing layer is formed by a layer of a plurality of clusters, whereby each cluster is formed by dye molecules and each dye molecule in the cluster is bonded to its adjacent dye molecules,
- wherein the light absorbing layer does not contain dye molecules disposed or absorbed on surfaces of semiconducting particles or a semiconducting layer,
- wherein the light absorbing layer is essentially a monolayer of the clusters,
- wherein spaces are formed between the clusters, and
- wherein the working electrode further comprises a conducting medium that fills the spaces between the clusters.
