Fluorene-based cathode interlayer polymers for high performance solution processed organic optoelectronic devices

TL;DR: It is shown that a further neutral polymer, namely poly(2-ethyl-2-oxazoline) (PEOz) can be successfully used as a dipole layer and increases the effective work function at the electron-collecting interface within inverted solar cells and thermal annealing of PEOz layer leads to a state-of-the-art 10.74% efficiency.

TL;DR: It is suggested that palladium precatalysts could bridge the gap between the rich array of structures utilized in organic electronics and what can be polymerized in a living, chain-growth fashion via CTP, based on their huge versatility in the small-molecule cross-coupling literature.

TL;DR: In this article, an alcohol soluble polymer, poly[(9,9-bis(3′-(N,N-diethylamino)propyl)-2,7-fluorene)-alt 2,7-(9, 9-dioctylfluorene)] (PFN), is introduced to the Al/n-Si interface to improve the contact property, resulting in a remarkable reduced work function of the Al electrode and thus a good ohmic contact.

TL;DR: Research in the use of organic polymers as active semiconductors in light-emitting diodes has advanced rapidly, and prototype devices now meet realistic specifications for applications.

TL;DR: In this article, the authors presented a review of several organic photovoltaics (OPV) technologies, including conjugated polymers with high-electron-affinity molecules like C60 (as in the bulk-heterojunction solar cell).

TL;DR: In this article, the authors showed that PFN can be incorporated into polymer light-emitting devices (PLEDs) to enhance electron injection from high-work-function metals such as aluminium (work function w of 4.3 eV) and gold (w ¼ 5.2 eV).

TL;DR: Tandem solar cells, in which two solar cells with different absorption characteristics are linked to use a wider range of the solar spectrum, were fabricated with each layer processed from solution with the use of bulk heterojunction materials comprising semiconducting polymers and fullerene derivatives.
