Thickness-Insensitive Anode Interface Layer for High-Efficiency Organic Solar Cells.

Thickness-insensitive anode interface layer materials are extremely crucial for commercial applications of organic solar cells (OSCs). Here, we have demonstrated a solution-processed and thickness-insensitive anode interfacial layer PCPDT-2Ph-H and employed it in large-area OSCs. The power conversion efficiency (PCE) of a PM6:Y6 device with a 0.

Printable Hole Transport Layer for 1.0 cm Organic Solar Cells.

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, PCPDTKH-TT. The PM6:Y6:PCBM device with PCPDTKH-TT as an HTL exhibits a power conversion efficiency (PCE) of 16.
