A vacuum-deposited organic solar cell employing this novel donor-acceptor-acceptor (D-A-A) donor molecule; DPDCPB; combined with the electron acceptor C60/ C70 achieved a record-high power conversion efficiency (PCE) of 5.6%.

Device structure:
MoO₃ (30nm) / DPDCPB (7nm) / DPDCPB:C70 (40nm) / C70 (7nm) / BCP (10nm) / Ag (150nm)

Device performance:

• JSC = 11.45 mA/cm²
• VOC = 1.0 V
• FF = 0.5
• PCE = 5.6%
