dc.description.abstract | The layer-by-layer (LBL) processing approach has recently been under intensive investigation to fabricate efficient polymer solar cells (PSCs) reconsidering its many positive aspects over the bulk-heterojunction configuration. Moreover, with recently reported successful solid additives as morphology controllers, they are becoming key elements for high-performance PSCs; however, their application in LBL systems has been scarce. Herein, we carry out a comprehensive investigation into the effect of benzothiadiazole (BT) and its fluorinated analogs (FBT and 2FBT) as solid additives on the device performance of a PM6/Y6-based LBL platform. The use of FBT in the PM6 donor layer results in a suitable morphology that ensures efficient charge transport/generation properties and suppresses recombination loss, boosting the photovoltaic performance of the LBL device. These intriguing results prompt us to further study the FBT treatment in other LBL systems (PTQ10/Y6 and PM6/BTP-eC9), leading to a considerable efficiency of up to 17.71% with low inevitable convolution arising from the molecular weight variations of the used polymers. Besides, we also demonstrate efficient large-area FBT-processed LBL PSCs (efficiencies of 16.10% (0.92 cm(2)) and 10.93% (2.50 cm(2))) with high device reproducibility. This study is not only invaluable in shaping our understanding of LBL PSCs, but also provides the possibility of overcoming their device-to-device variations in both small- and large-area single cells. | - |
