Currently, most of the hole transport layers (HTLs) of organic solar cells (OSCs) are unable to meet the requirements of printing preparation, which imposes restrictions on the commercial process of the OSCs severely. Here, we report a printable HTL, PCPDTK_0.50H_0.50-TT. The PM6:Y6:PC₇₁BM device with PCPDTK_0.50H_0.50-TT as an HTL exhibits a power conversion efficiency (PCE) of 16.3% (with an area of 0.04 cm²). More importantly, the PCE of the device is up to 10.2%, with an area of 1.0 cm² prepared by the wire-bar coating PCPDTK_0.50H_0.50-TT HTL, which is in favor of the printing fabrication of the OSCs. In view of the superiorities of the large-area printing and the impressive PCE, we believe that PCPDTK_0.50H_0.50-TT should be a potential HTL for industrial production of OSCs.

适用于1.0 cm ²有机太阳能电池的可印刷空穴传输层

当前，有机太阳能电池（OSC）的大多数空穴传输层（HTL）不能满足印刷准备的要求，这严重限制了OSC的商业生产。在这里，我们报告了可打印的HTL PCPDTK _0.50 H _0.50 -TT 。以PCPDTK _0.50 H _0.50 -TT作为HTL的PM6：Y6：PC ₇₁ BM装置的功率转换效率（PCE）为16.3％（面积为0.04 cm ²）。更重要的是，器件的PCE高达10.2％，通过线棒涂层PCPDTK _0.50 H _0.50制备的面积为1.0 cm ²-TT HTL，它有利于OSC的印刷制造。考虑到大面积印刷的优势和令人印象深刻的PCE，我们认为PCPDTK _0.50 H _0.50 -TT应该是OSC工业生产的潜在HTL。
