FIELD: manufacturing technology.
SUBSTANCE: invention relates to the technology of creating thin-film environmentally friendly solar cells and can be used to create flexible solar cells based on CdTe, CIGS or CZTS (Se). Polyimide film is pre-annealed in vacuum at T = 300–350 °C, then in the first stage, the molybdenum layer is precipitated at a pressure p1 > 6 × 10-3 mmHg, and on the second – with p2 = (2 ÷ 6) × 10-3 mmHg. Layers put in the ratio d1 ≥ d2, where d1 – thickness of the first layer, d2 – thickness of the second layer.
EFFECT: invention allows to obtain coatings that are stable in a liquid medium, with acceptable adhesion and resistivity on polyimide substrates.
