Abstract

The invention provides a suitable method and an appropriate, PV film structure. This aim is achieved by a room temperature method in which aqueous dispersions are printed onto a substrate and cured by an accompanying reaction. The accompanying reaction forms gradients and also nanoscale structures at the film boundaries, which produce a PV active film having standard performance and a higher stability. At around 10% efficiency, stability and no initial loss in performance in the climatic chamber test can be obtained and over a 20 year test period, consistently less fluctuation can be achieved. The method is free from tempering or sintering steps, enables the use of technically pure, advantageous starting materials and makes the PV film structure available as a finished, highly flexible cell for a fraction of the typical investment in production or distribution.
