作为低成本和可持续的能量收集技术的有机光活性材料（OPV）的期望属性要求使用非卤化溶剂加工用于光活性层（PAL）材料，优选具有低合成复杂性（SC）并且不损害功率转换效率（PCE）。尽管它们的PCE创纪录，但与非富勒烯受体组合的大多数供体-受体共轭共聚物由于它们的高成本和SC而仍然远未升级。在这里，我们提出了用于有机太阳能电池的PAL的非卤化和低SC油墨制剂，其包含分别作为供体和受体材料的PTQ 10和PC61 BM，在1个太阳下在刮刀涂覆的装置中显示出7.5%的创纪录PCE，在室内LED条件下为19.9%。我们进一步研究了PAL与5种不同的电子传输层（ETL）在倒置结构中的兼容性。我们确定商业ZnO基制剂与甲醇基聚乙烯亚胺-Zn（PEI-Zn）螯合ETL油墨一起是户外条件下最合适的夹层，提供高达74%的填充因子和优异的厚度公差（ETL高达150 nm，PAL>200 nm）。在室内环境中，SnO 2显示出上级性能，因为它不需要UV光活化。通过层压完全在空气中制造的半透明设备显示室内PCE超过10%，同时分别在400和350小时的热应力和光应力后保持超过80%的初始性能。因此，PTQ 10：PC61 BM结合PEI-Zn或SnO 2目前被定位为低成本、多用途OPV模块工业化的有前途的系统。一种用于有机太阳能电池的光活性层的非卤化和低合成复杂性的油墨配方，在1个太阳下在刮刀涂覆的装置中显示出7.5%的创纪录PCE，在室内LED照明下显示出19.9%的创纪录PCE。
The desired attributes of organic photovoltaics (OPV) as a low cost and sustainable energy harvesting technology demand the use of non-halogenated solvent processing for the photoactive layer (PAL) materials, preferably of low synthetic complexity (SC) and without compromising the power conversion efficiency (PCE). Despite their record PCEs, most donor–acceptor conjugated copolymers in combination with non-fullerene acceptors are still far from upscaling due to their high cost and SC. Here we present a non-halogenated and low SC ink formulation for the PAL of organic solar cells, comprising PTQ10 and PC61BM as donor and acceptor materials, respectively, showing a record PCE of 7.5% in blade coated devices under 1 sun, and 19.9% under indoor LED conditions. We further study the compatibility of the PAL with 5 different electron transport layers (ETLs) in inverted architecture. We identify that commercial ZnO-based formulations together with a methanol-based polyethyleneimine-Zn (PEI-Zn) chelated ETL ink are the most suitable interlayers for outdoor conditions, providing fill factors as high as 74% and excellent thickness tolerance (up to 150 nm for the ETL, and >200 nm for the PAL). In indoor environments, SnO2 shows superior performance as it does not require UV photoactivation. Semi-transparent devices manufactured entirely in air via lamination show indoor PCEs exceeding 10% while retaining more than 80% of the initial performance after 400 and 350 hours of thermal and light stress, respectively. As a result, PTQ10:PC61BM combined with either PEI-Zn or SnO2 is currently positioned as a promising system for industrialisation of low cost, multipurpose OPV modules. A non-halogenated and low synthetic complexity ink formulation for the photoactive layer of organic solar cells, showing a record PCE of 7.5% in blade coated devices under 1 sun and 19.9% under indoor LED illumination.
