Abstract:

Non-fullerene small molecule acceptor (ITIC) is introduced into the binary polymer solar cells (PBTIBDTT:PCBM[70]) to build ternary polymer solar cells, which achieves power conversion efficiency (PCE) of 10.95% with more than 200 nm thickness of photoactive layers. The ternary polymer solar cells are further fabricated by spray coating method, and realize 9.06% of PCE. The high efficiency ternary polymer solar cells fabricated by spray coating are suitable for the roll-to-roll printing, exhibiting great application prospects.

Key words: ternary polymer solar cells, non-fullerene small molecule acceptor, thick-film photoactive layer, spray coating, roll-to-roll printing
