在现有的可再生独立能源中，半透明（ST）太阳能电池由于能够集成到建筑物或车辆的窗户中而受到关注。为了实现实用的发电和美观的外观，我们制造了 PTB7:PC ₇₁基于 BM 的 ST 聚合物太阳能电池采用完全无真空和低成本的制造方法。可以从银纳米线和基于导电聚合物的透明层压顶部电极实现完全无真空制造，从而通过简单的热压层压步骤实现与下面的聚合物体异质结层的完全和具体的电接触。此外，对于在层压电极和聚合物层之间插入适当的空穴提取中间层，具有层压电极的 ST 太阳能电池提供了 4.36% 的最佳功率转换效率 (PCE) 和 53.9% 的填充因子 (FF) . 作为比较，还制造了具有金属顶部电极的不透明太阳能电池，提供了 9.07% 的最佳 PCE 和 65.4% 的 FF。然而，由于其卓越的光学特性，这些 ST 太阳能电池的劣质发电量可以通过其纯消色差吸引力来弥补。进行详细的光学分析以评估基于层压电极的 ST 太阳能电池在发电窗应用中的兼容性。ST太阳能电池没有表现出明显的光腔共振效应，具有极好的视觉外观，具有消色差的感觉，是一种窗口照明光源，亮度为38.1%，CCT为6480 K，D65下一般显色指数为95.5，是标准日光光源。进行详细的光学分析以评估基于层压电极的 ST 太阳能电池在发电窗应用中的兼容性。ST太阳能电池没有表现出明显的光腔共振效应，具有极好的视觉外观，具有消色差的感觉，是一种窗口照明光源，亮度为38.1%，CCT为6480 K，D65下一般显色指数为95.5，是标准日光光源。进行详细的光学分析以评估基于层压电极的 ST 太阳能电池在发电窗应用中的兼容性。ST太阳能电池没有表现出明显的光腔共振效应，具有极好的视觉外观，具有消色差的感觉，是一种窗口照明光源，亮度为38.1%，CCT为6480 K，D65下一般显色指数为95.5，是标准日光光源。

Fully vacuum-free semitransparent polymer solar cells for power-generating window with pure achromatic appealing

Among the existing renewable independent energy sources, semitransparent (ST) solar cells have attracted attention owing to their ability to be integrated into the windows of buildings or vehicles. To realize not only practical electricity production but also esthetic appearance, we fabricated PTB7:PC₇₁BM-based ST polymer solar cells via fully vacuum-free and low-cost manufacturing methods. Fully vacuum-free manufacturing could be achieved from a silver nanowire and conductive polymer-based transparent lamination top electrode, thereby achieving complete and concrete electrical contact with the underlying polymer bulk-heterojunction layer through a simple hot-press lamination step. In addition, for the insertion of an appropriate hole-extracting interlayer between the lamination electrode and polymer layer, ST solar cells with a lamination electrode provided the best power conversion efficiency (PCE) of 4.36% with a fill factor (FF) of 53.9%. For comparison, opaque solar cells with a metal top electrode were also fabricated, providing the best PCE of 9.07% with an FF of 65.4%. However, the inferior electricity production of these ST solar cells can be compensated for by its pure achromatic appeal owing to its superior optical properties. Detailed optical analysis was performed to evaluate the compatibility of the lamination electrode-based ST solar cells for power-generating window applications. ST solar cells did not exhibit a noticeable optical cavity resonance effect, resulting in an extremely good visual appearance with achromatic sensation and a window illumination source with luminosity of 38.1%, CCT of 6480 K, and general CRI of 95.5 under D65, which is a standard daylight illuminant.
