2,4-Bis[4-(N,N-diisobutylamino)-2,6-dihydroxyphenyl] squaraine

Description	2,4-Bis[4-(N,N-diisobutylamino)-2,6-dihydroxyphenyl] squaraine (DIB-SQ) is used as an electron donor in solution processed photovoltaic cells.DIB-SQ increases the power conversion efficiency (PCE) because it can harvest more photons in the low-energy range and also increases excition dissociation, energy transfer and charge carrier transport in ternary blend films in bulk heterjunction polymer solar cells.
