1. A PV layer sequence obtained by a room temperature process without tempering or sintering steps wherein:
on a flexographic printing machine
using technical grade purity starting materials
(a) the PV layer sequence comprising a metallic component was printed as a thin layer sequence at least including contact electrodes at room temperature in a continuous printing process,
(b) at least one aqueous solution and/or mixing comprising electrically conducting and/or semiconducting inorganic agglomerates was applied by printing and by concomitant chemical reaction, comprising surfacial oxidation of the metallic component, hardened to afford a PV-active layer, wherein in turn
(c) during the reaction nanoscale structures comprising networks, at least one structure selected from the group consisting of chains, network tubes, vacancies, pores were formed in the PV layer sequence.
