%X CdSe薄膜在许多应用领域都有广泛应用。在光催化领域，CdSe薄膜可以吸收光能并产生电子空穴对，从而促进光催化反应的进行。在生物医学领域，CdSe薄膜可以用于制备生物标记物和荧光探针，用于细胞成像、分子探测和生物传感等的应用中。在光电子学领域，CdSe薄膜因其优异的光电特性应用于太阳能电池的光吸收层，光传感器、光检测器和光放大器等光电子学器件中。本文通过CdSe薄膜制备理论分析其光学特性，制备CdSe太阳能吸收薄膜。针对其作为太阳能电池吸收薄膜的性能要求，采用G|2HL|A双层减反射膜系作为母膜系，以CdSe作为高折射率材料，SiO<sub>2</sub>、MgF<sub>2</sub>、HfO<sub>2</sub>分别作为低折射率材料进行膜系设计，并通过数据对比发现HfO<sub>2</sub>效果最好，通过设计降低反射率提高透射率和吸收率指标，选择可变度量法进行优化后，使其透过率和吸收率获得明显提升。设计结果表明：在380~780 nm波段，透过率高于30%，吸收率高于60%；在780~1000 nm波段，透过率高于65%，吸收率高于25%。设计要求值为保证镀制容差进行了透过指标溢出设计，数据表明设计的膜系能很好地满足薄膜性能需求，促进CdSe薄膜在光电子学领域更广泛的应用。<br />
CdSe thin films have wide applications in many fields. In the field of photocatalysis, CdSe thin films can absorb light energy and generate electron-hole pairs, thus promoting the progress of photocatalytic reactions. In the field of biomedicine, CdSe thin films can be used to prepare biomarkers and fluorescent probes for applications such as cell imaging, molecular detection, and biosensing. In the field of optoelectronics, CdSe thin films are applied in solar cell light absorption layers due to their excellent photoelectric properties, such as light sensors, light detectors, and optical amplifiers. In this paper, the optical properties of CdSe solar absorption thin films are analyzed through the theory of CdSe thin film preparation. For its performance requirements as a solar cell absorption film, a G|2HL|A dual-layer antireflection film system is used as the mother film system, with CdSe as the high refractive index material, SiO<sub>2</sub>, MgF<sub>2</sub>, and HfO<sub>2</sub> as low refractive index materials for film system design. Through data comparison, it is found that HfO<sub>2</sub> has the best effect. By designing to reduce reflectivity and improve transmission and absorption indicators, a variable metric method is used to optimize the film system, resulting in significant improvements in transmission and absorption rates. The design results show that in the 380~780 nm wavelength band, the transmission rate is higher than 30%, and the absorption rate is higher than 60%. In the 780~1000 nm wavelength band, the transmission rate is higher than 65%, and the absorption rate is higher than 25%. The design requirements value is a transmission index overflow design to ensure the plating tolerance. The data shows that the designed film system can well meet the film performance requirements and promote the wider application of CdSe thin films in the field of optoelectronics.
