A ZnO thin-film that comprised a ZnO monolayer close-packed structure embedded in ZnO sol-gel was fabricated. The structure contained ZnO spheres of various sizes. At normal incidence, the mean optical transmittance of the thin-film was 60% in the visible region when the structure contained spheres with a diameter of 300 nm. An average haze ratio of 80% was obtained from the thin-film when the structure was formed using 500 nm-diameter spheres. The thin-film exhibits broad-band transparency and a high haze ratio. It can be used as a light-trapping structure in an ultrathin solar cell.
制备了一种氧化锌薄膜，其包含嵌入氧化锌溶胶 - 凝胶中的氧化锌单层密堆积结构。该结构包含各种尺寸的氧化锌球体。在正入射时，当结构包含直径为300nm的球体时，薄膜在可见光区域的平均光学透过率为60%。当使用直径500nm的球体形成该结构时，薄膜的平均雾度比为80%。该薄膜具有宽带透明度和高雾度比。它可用作超薄太阳能电池中的光捕获结构。
