New developments in non-fullerene small molecule acceptors for polymer solar cells
This review describes developments of non-fullerene small molecular acceptors in solar cells since 2015, including rylene imide, indacenodithiophene and diketopyrrolopyrrole.
Side-chain engineering of perylenediimide-vinylene polymer acceptors for high-performance all-polymer solar cells
The performance of a PDI-vinylene polymer acceptor in an all-PSC is optimized by side-chain engineering. The best average PCE of 7.40% is obtained with a medium side-chain length.
Significantly improving the efficiency of polymer solar cells through incorporating noncovalent conformational locks
The power conversion efficiency of polymer solar cells was significantly enhanced through introducing conformational locks into the backbone of polymers.
Synthesis and photovoltaic properties of three different types of terpolymers
A series of terpolymers (Random, Regular and Block) based on dithienylphenylene, difluorobenzothiadiazole and dicyanobenzothiadiazole moieties were synthesized, and their optical, electrochemical, morphological, electrical and photovoltaic properties were studied.
High open-circuit voltage ternary organic solar cells based on ICBA as acceptor and absorption-complementary donors
A high open-circuit voltage of 0.98 V in ternary organic solar cells is achieved by using ICBA as an acceptor and two absorption-complementary donors.
A perylene diimide based polymer: a dual function interfacial material for efficient perovskite solar cells
An n-type semiconducting copolymer of perylene diimide and dithienothiophene (PPDIDTT) is used as a dual function interfacial layer to modify the surface of perovskite films in inverted perovskite solar cells, which exhibit higher efficiency and better stability.
Controlled self-aggregation of perylene bisimide and its application in thick photoconductive interlayers for high performance polymer solar cells
Asymmetric perylene bisimide enables a thick photoconductive cathode interlayer (100 nm), even the doping concentration is varied from 0.5 wt% to 5 wt%.
Novel donor–acceptor type conjugated polymers based on quinoxalino[6,5-f]quinoxaline for photovoltaic applications
Three novel conjugated polymers based on 2,3,8,9-tetrakis(3-(alkoxy)phenyl)-6,12-di(thiophen-2-yl)-2,3,8,9-tetrahydroquinoxalino[6,5-f]quinoxaline (DTNQx) were designed and synthesized, and were applied in photovoltaic cells.
Design of charge transporting grids for efficient ITO-free flexible up-scaled organic photovoltaics
Grids were integrated onto a top-illumination device with ultra-thin Ag as the TE: grid B further improved the device efficiency by ∼7% compared with grid A due to the shadow loss reduction.
