1. A method for preparing an absorbing layer of a solar cell, comprising:

  • providing a substrate, an absorbing layer precursor being loaded on the substrate, and the absorbing layer precursor comprising at least one group XIV element;

    providing a solid vapor source, the solid vapor source containing a group XIV element the same as the group XIV element in the absorbing layer precursor, the solid vapor source corresponding to the absorbing layer precursor, and the solid vapor source and the absorbing layer precursor being kept apart by a distance; and

    performing a heating process, so that the absorbing layer precursor forming an absorbing layer on the substrate, the solid vapor source being vaporized and generating a gas of the group XIV element, and the gas of the group XIV element inhibiting the effusion of the group XIV element of the absorbing layer precursor so that the proportion of the group XIV element in the formed absorbing layer being consistent.
