Direct (Hetero)arylation: A Tool for Low-Cost and Eco-Friendly Organic Photovoltaics

ACS Applied Polymer Materials, Journal Year: 2020, Volume and Issue: 3(1), P. 2 - 13

Published: Sept. 30, 2020

Organic photovoltaics have attracted much attention in the past few years, mainly due to their ability be fully printed at low cost and large scale. However, organic semiconductors utilized as active layer are typically synthesized using Migita–Stille or Suzuki–Miyaura cross-coupling, which is not efficient may bring toxicity concerns. In search for atom-economical synthesis, direct (hetero)arylation polymerization (DHAP) enables activation of aromatic C–H bonds, both reducing synthetic steps monomers toxic reaction byproducts. this issue, we will discuss recent contributions on synthesis toward mass production photovoltaic materials. The impact DHAP material efficiency addressed compared conventional coupling methods. ongoing improvements discussed, becomes more sustainable higher scale materials observed having quality.

Molecular Engineering for Large Open-Circuit Voltage and Low Energy Loss in Around 10% Non-fullerene Organic Photovoltaics

ACS Energy Letters, Journal Year: 2018, Volume and Issue: 3(4), P. 1028 - 1035

Published: March 27, 2018

Recent efforts in organic photovoltaics (OPVs) have been devoted to obtaining low-bandgap non-fullerene acceptors (NFAs) for high photocurrent generation. However, the low-lying lowest unoccupied molecular orbital (LUMO) level narrow bandgap NFAs typically results a small energy difference (ΔEDA) between LUMO of acceptor and highest occupied (HOMO) donor, leading low open-circuit voltage (VOC). The trade-off ΔEDA generation significantly limits simultaneous enhancement both VOC short-circuit current density (JSC). Here, we report new medium-bandgap NFA, IDTT-T, containing weakly electron-withdrawing N-ethyl thiabarbituric acid terminal group on each end indacenodithienothiophene (IDTT) core. When paired with benchmark PTB7-th polymer absorption spectral coverage was realized. OPV devices yield 1.01 V, corresponding loss 0.57 eV around 10% efficiency single-junction NFA OPVs. design demonstrates working principle concurrently increase PCE bulk fullerene-free heterojunction

Borane Incorporation in a Non-Fullerene Acceptor To Tune Steric and Electronic Properties and Improve Organic Solar Cell Performance

ACS Applied Energy Materials, Journal Year: 2019, Volume and Issue: 2(2), P. 1229 - 1240

Published: Jan. 4, 2019

Herein we study the effects of borane incorporation in a perylene diimide (PDI)-based non-fullerene acceptor (NFA). We have previously demonstrated that PDI-bithiophene-PDI ((PDI)2Th2) compound can be synthesized via direct (hetero)arylation techniques and is easily modified to incorporate phosphole bithiophene core ((PDI)2Th2PO) tune electronic geometric properties. In this work, analogue ((PDI)2Th2B) organoboron moiety heavily influences optical, electronic, To determine functionalization on device performance, green solvent solution-processed bulk-heterojunction solar cells were fabricated using medium-gap donor polymer TTFQx-T1 each PDI as NFA, respectively. Devices with new borane-containing provided highest efficiency, more than twice for other compounds, which was attributed highly twisted structure allowing favorable active-layer morphology formed.
