Abstract
The invention relates to an electrode (10) for photoelectric catalysis, comprising a supporting layer (1) on which a catalytic layer (2) is arranged, which comprises particles (3) from a first semiconductor material, and a method for the production of said electrode and a solar cell with said electrode. It is provided that the catalytic layer (2) further features a matrix (4) consisting of a second semiconductor material, which at least partially surrounds the particles.

An electrode (10) for photoelectric catalysis, comprising a supporting layer on which a catalytic layer is arranged, which comprises particles from a first semiconductor material, characterized in that the catalytic layer further features a matrix from an amorphous material which at least partially surrounds the particles.
A method for producing an electrode for photoelectric catalysis, comprising the following steps:
- a:
- Preparing a suspension of particles in a solvent and bringing the suspension into contact with a supporting layer,
- b:
- Applying a voltage pulse between the supporting layer and the suspension for depositing a layer of particles on the supporting layer, and
- c:
- Reducing the diameter of the suspended particles, and
- single repetition of step (b) or multiple repetition of steps (b) and (c).
