This work reports experimental evidence of a photovoltaic effect in transparent UV‐selective Zn(O,S)‐based heterojunctions. Zn(O,S) has a strong interest for the development of UV‐selective solar cells with high transparency in the visible region, required for the development of nonintrusive building‐integrated photovoltaic (BIPV) elements as transparent solar windows and glass‐based solar façades. By anion alloying, Zn(O,S) mixed crystal absorbers can be fabricated with different sulfur content across the whole compositional range. This allows adjustment of the bandgap of the absorbers in the 2.7–2.9 eV region, maximizing absorption in the UV, while keeping a high level of transparency. Zn(O,S) alloys with composition corresponding to S/(S + O) content ratios of 0.6 are successfully grown by sputtering deposition, and first glass/FTO/NiO/Zn(O,S)/ITO device prototypes are produced. The resulting devices present an average visible transmittance (AVT) of 75% and present photovoltaic effect. By introducing a thin C₆₀ film as electron transport layer (ETL), charge extraction is enhanced, and devices show an efficiency of 0.5% and an AVT > 69%. The transparency of these devices can potentially allow for their ubiquitous installation in glazing systems as part of nonintrusive BIPV elements or to power Internet of Things (IoT) devices and sensors as an integrated transparent component.

紫外线选择性光学透明的Zn（O，S）基太阳能电池

这项工作报告了在透明的基于紫外线的选择性Zn（O，S）异质结中产生光伏效应的实验证据。Zn（O，S）对开发在可见光区域具有高透明度的紫外线选择性太阳能电池具有浓厚的兴趣，这是开发非侵入式建筑集成光伏（BIPV）元素（如透明太阳能窗口和玻璃基太阳能）所必需的外墙。通过阴离子合金化，可以制造在整个组成范围内具有不同硫含量的Zn（O，S）混合晶体吸收剂。这样可以在2.7–2.9 eV范围内调节吸收剂的带隙，从而最大程度地吸收紫外线，同时保持较高的透明度。通过溅射沉积成功地生长了组成对应于S /（S + O）含量比为0.6的Zn（O，S）合金，并制备了第一块玻璃/ FTO / NiO / Zn（O，S）/ ITO器件原型制作完成。所得器件的平均可见光透射率（AVT）为75％，并具有光伏效应。通过引入薄C₆₀膜作为电子传输层（ETL），增强了电荷提取，器件显示0.5％的效率和AVT> 69％。这些设备的透明性可能允许将它们作为非侵入式BIPV元素的一部分无处不在地安装在玻璃系统中，或者作为集成的透明组件为物联网（IoT）设备和传感器供电。
