关于钙钛矿太阳能电池（PSCs）在商业产品中的应用，成本和毒性问题一直是激烈争论的焦点。第一个瓶颈可以通过消除顶部金属电极（通常是金）和下面的空穴传输材料，并用一层厚的导电碳取代两者来克服，就像所谓的碳基PSCs （C - PSCs）一样。第二个问题与铅的存在有关，可以通过采用其他基于毒性较小的金属成分的钙钛矿结构来解决。一个有趣的例子是双钙钛矿Cs2AgBiBr6，它目前仍然缺乏铅基同类产品的突出光电性能，但对环境因素非常稳定。在这项工作中，报道了碳电极在Cs2AgBiBr6基C - PSCs上的加工，从废轮胎水热回收的碳材料的无添加剂异丙醇油墨开始，在正常环境条件下采用高通量超声波喷涂方法。通过这种高度可持续的方法，确保了废旧轮胎从报废到报废的有价值的一步，获得了提供创纪录的1.293 V开路电压的设备，这可能在未来代表为室内物联网生态系统供电的超廉价解决方案。废物的终结：废轮胎被转化为导电炭黑，用作无铅钙钛矿太阳能电池的抽孔触点。这种碳电极是由纯异丙醇喷涂而成的，不含添加剂，使整个过程高度可持续。由于在钙钛矿/碳界面处建立了内置电位，由此产生的光伏器件提供了非常高的开路电压。
Costs and toxicity concerns are at the center of a heated debate regarding the implementation of perovskite solar cells (PSCs) into commercial products. The first bottleneck could be overcome by eliminating the top metal electrode (generally gold) and the underlying hole transporting material and substituting both with one single thick layer of conductive carbon, as in the so‐called carbon‐based PSCs (C‐PSCs). The second issue, related to the presence of lead, can be tackled by resorting to other perovskite structures based on less toxic metallic components. An interesting case is that of the double perovskite Cs2AgBiBr6, which at present still lacks the outstanding optoelectronic performances of the lead‐based counterparts but is very stable to environmental factors. In this work, the processing of carbon electrodes onto Cs2AgBiBr6‐based C‐PSCs was reported, starting from an additive‐free isopropanol ink of a carbon material obtained from the hydrothermal recycling of waste tires and employing a high‐throughput ultrasonic spray coating method in normal environmental conditions. Through this highly sustainable approach that ensures a valuable step from an end‐of‐life to an end‐of‐waste status for used tires, devices were obtained delivering a record open circuit voltage of 1.293 V, which might in the future represent ultra‐cheap solutions to power the indoor Internet of Things ecosystem. End‐of‐waste: Waste tires are transformed into conductive carbon black for use as hole‐extracting contact in lead‐free perovskite solar cells. This carbon electrode is processed via spray‐coating from pure isopropanol with no additives, making the whole process highly sustainable. The resulting photovoltaic devices deliver a very high open‐circuit voltage due to the built‐in potential established at the perovskite/carbon interface.
