1. A kind of 1. new annealing way of CZTS films, it is characterised in that:

  • Include following steps:

    (1) 0.5g powder sulphur is placed in the closed side of the glass tube of single-ended closing, and CZTS films are placed in glass tube and leaned onThe open end of nearly glass tube, rubber tube is connected to by the open end of glass tube;

    (2) mechanical pump is opened, three direction valves is opened, glass tube is vacuumized, air is flowed along a direction, whenWhen pressure in glass tube is less than 1Pa, switch three direction valve directions, opening main valve makes air-flow along other direction through diffusion pumpFlowing;

    (3) when glass overpressure is less than 3.0 ×

    10-3Pa, open heating source and the open end of glass tube is heated, meltThe glass tube of change inwardly collapses under the action of external and internal pressure difference, finally completely encloses, obtained annealing specimen;

    (4) obtained annealing specimen is put in annealing furnace, annealed.
