Abstract

PV layer sequences and corresponding production methods which can reliably provide a PV function with a long service life despite very low production costs. This is achieved by a reactive conditioning process of inorganic particles as part of a room-temperature printing method; the reactive surface conditioning process adjusts the PV activity in a precise manner, provides a kinetically controlled reaction product, and can ensure the desired PV activity even when using technically pure starting materials with 97% purity. In concrete embodiments, particles are printed in composite so as to form sub-sections on a support. Each sub-section has a reductively treated section and an oxidatively treated section, and the sections have PV activity with opposite signs. The sections can be cascaded in rows via upper-face contacts, and a precise light-dependent potential sum can be tapped via a PV measuring group.
