New Pyridinium Ylide Dyes for Dye Sensitized Solar Cell Applications

Novel organic pyridinium ylide sensitizers (NO109-111) consisting of various anchoring groups were synthesized and characterized for applications in dye sensitized solar cells. Compared with the pyridine-N-oxide dye (NO108), the ylide sensitizers with strong electron-withdrawing acceptors exhibited dominant ultraviolet absorption properties and efficient binding abilities to the TiO2 surface. Among these dyes, the pyridinium ylide NO111 sensitized solar cell showed the highest efficiency (5.15%), which was improved to 7.41% by employing coadsorbent chenodeoxycholic acid.

Making benzotrithiophene derivatives dopant-free for perovskite solar cells: Step-saving installation of π-spacers by a direct C-H arylation strategy

Previously, benzotrithiophene (BTT)-based hole-transporting materials (HTMs) had to be doped with three chemical agents for high-efficiency perovskite solar cells (PSC). This work describes significant progress by which the first dopant-free BTT core-based HTM (YKP03) with EDOT spacers was readily accessed by step-saving direct C-H arylation. PSCs with dopant-free YKP03 showed promising efficiencies of up to 16.15% with potential long-term storage stability.

Perovskite hole transport material based on triptycene mother nucleus and preparation method thereof

The present invention discloses a perovskite hole transport material based on a triptycene mother nucleus and a preparation method thereof. The material is 2,6,14-tri(50-(N,N-bi(4-methoxyphenyl)aminophenol-4-yl)-3,4-ethylenedioxythiophene-2-yl)-triptycene. The preparation method has the advantages of mild synthesis conditions, simple steps, cheap and easily obtained synthetic raw materials, and low synthesis costs. The prepared material has a good thermal stability, solubility and film forming property. An ultraviolet-visible light absorption spectrum indicates the hole transport material based on the triptycene mother nucleus has a large conjugate structure, has a more suitable HOMO level (-5.08 eV) than that of a mainstream hole transport material Spiro-MeOTAD, and provides a strong driving force for hole transporting. The carrier mobility of the material measured by a space charge limiting current method is 8x10cm.Vs. The perovskite hole transport material has potential.

Embedding an electron donor or acceptor into naphtho[2,1-b:3,4-b′] dithiophene based organic sensitizers for dye-sensitized solar cells

An electron donor and acceptor, respectively, is embedded into naphtho[2,1-b:3,4-b′]dithiophene based organic sensitizers to tune their optoelectronic properties. The DSSC based on FNE52 containing an auxiliary electron acceptor displays a maximum power conversion efficiency of 8.2% and good long-term stability.
