“…To further probe charge carrier dynamics, the transient photocurrent (TPC) and transient photovoltage (TPV) are measured. The charge extraction time (τ ext ) is determined by fitting the TPC decays under short-circuit conditions (Figure c). , The PBB-F-based and PM6-based binary blend films exhibit the τ ext value of 0.93 and 1.12 μs. In contrast, the τ ext values of the ternary system are reduced to 0.91 μs.…”

Voltage loss is an inescapable problem in ternary polymer solar cells (PSCs) because of utilizing photovoltaic materials with complementary absorption. In this work, two donor structure (D1:D2:A) ternary PSCs comprising a poly[(2,6-(4,8-bis(5-(2-hexyldecyl-3-fluoro)thiophen-2-yl)-benzo[1,2-b:4,5-b′]dithiophene))-alt-(5,5-(2,6-di-2-thienyl)-4,8-bis(5-(2-hexyldecyl)thiophen-2-yl)benzo[1,2-d:4,5-d′]bis(thiazole))] (PBB-F), poly[(2,6-(4,8-bis(5-(2-ethylhexyl-3-fleoro)thiophen-2-yl)-benzo[1,2-b:4,5-b′]dithiophene))-alt-(5,5-(1′,3′-di-2-thienyl-5′,7′-bis(2-ethylhexyl)benzo[1′,2′-c:4′,5′-c′]dithiophene-4,8-dione)] (PM6), and 3,9-bis(2-methylene-((3-(1,1-dicyanomethylene)-6,7-difluoro)-indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2′,3′-d′]-s-indaceno[1,2-b:5,6-b′]dithiophene) (IT-4F) system exhibit low voltage loss with no cascade energy level structure, whereas the corresponding devices acquire enhanced power conversion efficiency (PCE) of 15.08%. The increased PCEs are ascribed to the improved phase separation after incorporating PM6, and thus, the charge recombination loss can be suppressed and the charge transport and extraction can be enhanced. Importantly, Kelvin probe force microscopy (KPFM) of two donor material blend films on poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) or ZnO (under dark and 638 nm irradiation conditions) is performed to check the exciton separation dynamics of photovoltaic materials, and the results intuitively demonstrated that holes can efficiently transfer from the high highest occupied molecular orbital (HOMO) of donor PM6 to the low HOMO of donor PBB-F, which ensures unblocked hole transport channels and thus induces low voltage loss. Besides, the D1:D2:A PSCs showed broad component tolerance from 10 to 50% blend ratios for PM6, which is conducive to large-scale commercialization fabrication conditions.

“…nanomaterials, the power conversion efficiencies (PCEs) of organic solar cells (OSCs) have improved extremely quickly over the past few decades and are presently close to 20%. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] However, these efficiencies are still lower than those of crystalline silicon and other inorganic solar cell technologies under standard illumination. [15][16][17][18][19] However, organic semiconductors offer several advantages that make these materials attractive for purposes other than large-scale power generation.…”

“…[58] Later, it is shown that due to the development of the new non-fullerene acceptor (NFA) and D-A conjugate polymer, device engineering, and improvement in the surface morphology, the efficiency of the BHJ OSCs has accomplished significant evolution with an efficiency more than 19%. [37,[59][60][61][62][63][64][65][66][67] However, to realize the high PCE compared to other competitive technologies, enhancing the light-harvesting ability of the active layer is the prerequisite issue. Though, it is difficult to cover the full solar spectrum with a BHJ consisting of one donor and one acceptor due to the intrinsic light absorption properties of organic materials, which also imposes a limitation on the PCE improvement.…”
