FIELD: electricity.
SUBSTANCE: shortage of traditional printed PV-elements consists in fact that production of these elements often requires expensive stages of vacuum preparation and thermal hardening or baking, wherein the thin alloyed vacuum films are extremely susceptible to corrosion and contamination. Thus, the present invention provides overcoming these drawbacks and obtaining a suitable method and a corresponding PV film structure. This result is achieved by a method implemented at room temperature, in which aqueous dispersions are applied by printing on a substrate and cured by a concomitant reaction. Concomitant reaction generates gradients, as well as nanosized structures on film boundaries, which provides PV-active film with standard capacity and higher stability. It is possible to achieve constant efficiency of approximately 10 %, and without deterioration of characteristics in initial period of operation during testing in climatic chamber and during 20-year period of tests constantly with small change. Method does not include stages of tempering or baking, enables to use technically pure predominant raw materials and provides film PV-structure in form of completed extremely flexible element with only part of usual investments in production or distribution. For the first time PV film structures can be obtained completely similar to production of printed products.
EFFECT: present invention can offer extremely versatile applicability with respect to both production and use in all industries in which currently available thin PV films have been previously rejected as too expensive or too unstable.
