    • A quantum dot dye-sensitized solar cell (QDDSSC) including an anode, a cathode, and an electrolyte between the anode and the cathode is provided. The anode includes a semiconductor electrode layer adsorbed with a dye, a plurality of quantum dots distributed within the semiconductor electrode layer, and a plurality of metal nanoparticles distributed within the semiconductor electrode layer. Because the absorption spectra of the quantum dots, the dye, and the semiconductor electrode layer cover the infrared (IR), visible, and ultraviolet (UV) regions of the solar spectrum, IR to UV light in the solar spectrum can be effectively absorbed, and accordingly the conversion efficiency of the solar cell can be improved. Moreover, the metal nanoparticles can increase the light utilization efficiency.
    • 提供了在阳极和阴极之间包括阳极,阴极和电解质的量子点染料敏化太阳能电池(QDDSSC)。 阳极包括吸附有染料的半导体电极层,分布在半导体电极层内的多个量子点和分布在半导体电极层内的多个金属纳米颗粒。 由于量子点,染料和半导体电极层的吸收光谱覆盖了太阳光谱的红外(IR),可见光和紫外(UV)区域,因此可以有效吸收太阳光谱中的紫外光, 因此能够提高太阳能电池的转换效率。 此外,金属纳米粒子可以提高光的利用效率。
