Solution-processed small molecule (SM) solar cells have the prospect to outperform their polymer-fullerene counterparts. Considering that both SM donors/acceptors absorb in visible spectral range, higher expected photocurrents should in principle translate into higher power conversion efficiencies (PCEs). However, limited bulk-heterojunction (BHJ) charge carrier mobility (8%, and optimized DR3:ICC6:PCBM solar cells demonstrate long-term shelf stability (dark) for >1000 h, in 55% humidity air environment.
