Efficient Nanocrystal Photovoltaics with PTAA as Hole Transport Layer. [PDF]
The power conversion efficiency (PCE) of solution-processed CdTe nanocrystals (NCs) solar cells has been significantly promoted in recent years due to the optimization of device design by advanced interface engineering techniques. However, further development of CdTe NC solar cells is still limited by the low open-circuit voltage (Voc) (mostly in range

Substituted Polyfluorene-Based Hole Transport Layer with Tunable Solubility [PDF]
We report on the synthesis and electrical characterization of polyfluorene-triarylamine-based hole transport layers (HTLs). The solubility of the HTL can be tuned by adjustment of the chemical structure without loss of the charge transport properties. Double-layer polymer light-emitting diodes are constructed with an HTL that is not soluble in toluene ...

Polymer light‐emitting diodes with doped hole‐transport layers [PDF]
AbstractWe demonstrate a solution processed bi‐layer PLED based on poly(p‐phenylene vinylene) derivatives using orthogonal solvents. To lower the voltage drop the hole transport layer (HTL) based on poly[2,5‐bis(2′‐ethylhexyloxy)‐co‐2,5‐bis(butoxy)‐1,4‐phenylenevinylene] (BEH/BB‐PPV (1:3)) is doped with tetracyano‐tetrafluoro‐quinodimethane (F4TCNQ ...
