Abstract
In this work, two DTSiC-based nonfullerene acceptors (NFAs), (2,2'-((2Z,2'Z)-((12-(heptadecan-9-yl)-4,4,7,7-tetraoctyl-7,12-dihydro-4H-thieno[2',3':4,5]silolo[3,2-b]thieno[2',3':4,5]silolo[2,3-h]carbazole-2,9-diyl)bis(methaneylylidene))bis(3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile) (DTSiC-IC) and (2,2'-((5Z,5'Z)-((12-(heptadecan-9-yl)-4,4,7,7-tetraoctyl-7,12-dihydro-4H-thieno[2',3':4,5]silolo[3,2-b]thieno[2',3':4,5]silolo[2,3-h]carbazole-2,9-diyl)bis(methaneylylidene))bis(6-oxo-5,6-dihydro-4H-cyclopenta[c]thiophene-5,4-diylidene))dimalononitrile) (DTSiC-TC), are designed with various end groups (IC and TC). To explore the effect of end-group modifications, photovoltaic performance under AM 1.5G and indoor conditions are comprehensively studied. Compared with DTSiC-IC, DTSiC-TC manifests red-shifted and stronger absorption, downshifted lowest unoccupied molecular orbital (LUMO), and pronounced face-on packing characteristics. As we envisaged, the PM7:DTSiC-TC-based devices outperform the PM7:DTSiC-IC-based devices in both AM 1.5G and indoor (light-emitting diode (LED) 3000 K 1000 lux) conditions with overall higher JSC, FF, and power conversion efficiency (PCE). Furthermore, the PM7:DTSiC-TC-based devices achieve an outstanding PCE of 20.73% with a VOC of 0.87 V, a JSC of 0.095 mA/cm2, and an FF of 70.86%.

Abstract
Four pyrene-porphyrins were synthesized to study the isomer effect on the photovoltaic performance of dye-sensitized solar cells. One of these porphyrins is conjugated with a terminal pyrene, whereas the other three are each attached with a pyrene bearing an extra donor group. According to the positions of the extra donor and porphyrin core on pyrene, the 1,6-, 1,8-, and 2,7-isomers were compared for their fundamental and photovoltaic properties. For fundamental properties, UV-visible absorption, fluorescence emission, electrochemistry, and DFT calculations were carried out. For photovoltaic measurements, the seemingly inferior 1,8-isomer outperforms others with an overall efficiency of 10.30% under one-sun irradiation. Superior photovoltaic performance of the 1,8-isomeric dye may be related to the so-called umbrella effect. The findings of this work may provide insight into isomeric dye design for future applications.

Abstract
In this article, a fluorinated heptacyclic dithienocyclopentacarbazole (DTC)-based non-fullerene acceptor (NFA), DTC(4Ph)-4FIC, is synthesized and blended with J71, PBDB-T, and PBDB-TF, featuring complementary absorption and well-matched energy levels. The DTC(4Ph)-4FIC neat film exhibits face-on preference, whereas the nonfluorinated counterpart, DTC(4Ph)-IC, exhibits edge-on preference; this unique feature owing to fluorination in DTC-based NFAs is observed for the first time. More importantly, DTC(4Ph)-4FIC exhibits improved power conversion efficiencies (PCEs) of 10.92 and 10.41% in J71- and PBDB-T-containing devices, while the devices that employed DTC(4Ph)-IC afford PCEs of 7.76 and 9.48%, respectively. Because PBDB-TF is known to exhibit lower energy levels than J71 and PBDB-T, the corresponding device affords a VOC of 0.95 V, a JSC of 18.29 mA cm-2, a FF of 75.70%, and a PCE of 13.15%, which is 20 and 26% higher than J71- and PBDB-T-containing devices. Furthermore, the inverted device containing the PBDB-TF:DTC(4Ph)-4FIC blend is fabricated using cross-linkable fullerene (C-PCBSD) as the cathode interlayer, affording a decent PCE of 13.36%, with a VOC of 0.94 V, a JSC of 20.20 mA cm-2, and a FF of 70.42%.
