چکیده
Compared with Flu(DPP)2, the PCEs of devices based on A′–A–π–D–π–A–A′ type Flu(DPPsF)2 and Flu(DPPdF)2 increased by 51.4% 63.4%, respectively, which is due to synergistic effect extended conjugate design end-group fluorination.

Diketopyrrolopyrrole-based acceptor polymers for photovoltaic application.
Developing new acceptor materials as alternatives to fullerene acceptors remains a challenge in the field of organic photovoltaics. We report on the synthesis and optoelectronic properties of three acceptor polymers bearing diketopyrrolopyrrole units in the main chain (PA, PB and PC). Their performance as the acceptor material in bulk heterojunction solar cells using P3HT as the donor material ...
متن کاملSmall-molecule photovoltaics based on functionalized squaraine donor blends.
Two squaraine (SQ) donor molecules with different absorption bands are blended together for better coverage of the solar spectrum. The blend SQ device shows a significant improvement compared with single SQ donor devices. By applying a solvent annealing process and a compound buffer layer, a power-conversion efficiency of 5.9 ± 0.3% is achieved under 1 sun illumination.
متن کاملImproving the compatibility of fullerene acceptors with fluorene-containing donor-polymers in organic photovoltaic devices.
Fluorene-containing PCBM analogs have been synthesized and tested with a polyfluorene copolymer, PF10TBT, in organic photovoltaic devices resulting in an increase of ∼130 mV in the open circuit voltage compared to devices with PCBM as acceptor material.
متن کاملRhodanine dye-based small molecule acceptors for organic photovoltaic cells.
The solution-processable small molecules based on carbazole or fluorene containing rhodanine dyes at both ends were synthesized and introduced as acceptors in organic photovoltaic cells. The high energy levels of their lowest unoccupied molecular orbitals resulted in a power conversion efficiency of 3.08% and an open circuit voltage of up to 1.03 V.
متن کاملAn extended hesitant group decision-making technique based on the prospect theory for emergency situations
Throughout the present manuscript, we are going to introduce a novel group emergency decision-making technique in which the application of prospect theory explains the psychological behaviour of the decision maker who is affected by the hesitancy and uncertainty of cognition in decision making problems.\Instead of usual aggregation procedure, we implement here a new fusion technique that ...
