[0017] The preparation method of a kind of copper indium gallium selenide alloy of the present invention comprises the following steps:
[0018] S1: Feeding: Under certain pressure conditions, simple copper, indium, gallium, and selenium are used as raw materials. The four raw materials exist in the form of pellets or blocks. The four raw materials are based on the mass ratio of selenium: indium: gallium: copper = 15~100 : 50~180: 10: 37.7~298 Put selenium, indium, gallium, and copper into the crucible in turn, seal the crucible and place the crucible in a closed heat-resistant container;
[0019] S2: Vacuumize and remove oxygen: vacuumize the heat-resistant container to 1×10 -3 ~1Pa, then pass in an inert gas to 0.1~0.15 MPa, then evacuate to 1~10 Pa, remove all the oxygen in the heat-resistant container, and finally pass in an inert gas to adjust the pressure in the heat-resistant container to 1.3~3.0MPa;
[0020] S3: Heating: heat up to 750~900°C in the heat-resistant cont...
Embodiment 1
[0027] Take 5N selenium grain / block, 5N indium block, 5N gallium block, 5N copper grain / nail (1-5mm copper grain is suitable), according to the mass ratio selenium: indium: gallium: copper = 36:50:10:90 Ingredients 6000g, put the selenium material on the bottom layer of the high-purity graphite crucible, then put in indium and gallium, and finally put copper on the top layer, seal the crucible and put the crucible in a closed heat-resistant container, and then vacuumize the heat-resistant container to 1Pa, then pass high-purity nitrogen until the pressure inside the heat-resistant container is 0.1 MPa, then evacuate to below 10Pa, and finally pass high-purity nitrogen to adjust the pressure inside the heat-resistant container to 1.3MPa, and raise the temperature of the heat-resistant container to 750 ℃ and keep it warm for 30 minutes, then raise it to 1200 ℃ for 1 hour and keep it warm for 4 hours; after cooling down to 50 ℃ in the heat-resistant container, exhaust and release ...
