Abstract (en)
[origin: WO2016134704A1] A disadvantage of classic, printed PV film cells is that the production of these cells frequently calls for expensive vacuum preparations and thermal tempering or sintering steps, wherein the thin, doped vacuum-films are highly susceptible to corrosion and contamination. Thus the aim of the invention is to overcome these disadvantages and to provide a suitable method and an appropriate PV film structure. This aim is achieved by means of 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. For the first time, PV film structures can be produced completely analogously to the manufacture of a printed product. Therefore, the invention can offer an extremely versatile applicability with regard to both production and use in all fields in which established PV thin-films were previously rejected as too expensive or too instable.
