The power conversion efficiency (PCE) of organic solar cells (OSCs) has been gradually increasing over the past years, but these emerging photovoltaic devices still suffer from relatively short lifetimes. To promote circular economy and reduce costly electronic materials wastes, we explore the possibility of recycling durable zinc oxide coated indium tin oxide (ITO/ZnO) from nonfullerene OSCs through sequential ultrasonication in a series of solvents followed by thermal annealing. With the adequate cleaning sequence, the recycled ITO/ZnO substrates produce PCEs of 8.65%, a value comparable to the PCEs obtained with freshly prepared substrates (8.73%). Our results also indicate that isopropanol gradually removes the zinc oxide layer and should thus be avoided when attempting multiple successive recycling of the same substrate. ITO/ZnO substrates recycled 10 times with and without isopropanol yield PCEs of 5.14% and 7.93%, respectively. By optimizing the recycling procedure, we introduce a simple strategy to considerably increase the lifecycle of transparent electrode substrates employed in organic electronic devices and decrease the amount of wastes from the electronic industry.

使用回收的透明导电基板制造的高性能有机太阳能电池

在过去的几年中，有机太阳能电池（OSC）的功率转换效率（PCE）一直在逐渐提高，但是这些新兴的光伏设备的使用寿命仍然相对较短。为了促进循环经济并减少昂贵的电子材料浪费，我们探索了通过在一系列溶剂中依次进行超声处理然后进行热退火，从非富勒烯OSC中回收耐用的氧化锌涂覆的铟锡氧化物（ITO / ZnO）的可能性。通过适当的清洁程序，回收的ITO / ZnO基板产生的PCE为8.65％，该值可与PCE媲美用新鲜制备的底物（8.73％）获得。我们的结果还表明，异丙醇会逐渐去除氧化锌层，因此在尝试多次连续回收同一基材时应避免使用异丙醇。ITO / ZnO基材在有和没有异丙醇的情况下循环使用10次，其PCE分别为5.14％和7.93％。通过优化回收程序，我们引入了一种简单的策略来显着提高有机电子设备中使用的透明电极基材的生命周期，并减少电子行业产生的废物量。
