Cadmium telluride target material and preparation method thereof
The invention belongs to the field of solar cells, and discloses a preparation method of a cadmium telluride target material, which comprises the following preparation steps: mixing cadmium telluride and cuprous telluride, then loading into a mold, and pre-pressing and vacuumizing a vacuum pipe to obtain a blank body; and then the blank is subjected to vacuum sintering, heat preservation, pressurization and cooling, and the cadmium telluride target material is obtained. According to the method, the cadmium telluride powder and the cuprous telluride which are distributed according to a certain proportion gradient are combined, so that the resistivity in the prepared cadmium telluride target material is reduced, and the conductivity of the cadmium telluride film in the subsequent use process is improved; in addition, the invention also discloses the cadmium telluride target material which is prepared by the method.
本申请属于太阳能电池领域，公开了一种碲化镉靶材的制备方法，其制备步骤如下：先将碲化镉、碲化亚铜混合，然后装入模具，进行预压抽真空管得到胚体；然后再将胚体进行真空烧结，保温加压、降温，得到碲化镉靶材。该方法通过将按一定比例梯度分布的碲化镉粉末与碲化亚铜结合，使制得的碲化镉靶材内的电阻率降低，提高后续使用过程中碲化镉薄膜的导电性；此外，本申请还公开了一种碲化镉靶材，由上述方法制得。
