These polymers exhibit good electroninjection properties and low barrier energy between electrons and hole injection
to polymer, in the range of 0.
Dye-sensitized solar cells are a type of nanostructured solar cells whose mechanism is based on light absorption by the pigment molecules plus electron and hole injection
to a semiconductor and an electrolyte.
The most common conductive polymer used in OLEDs, typically for the hole injection
layer, is poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS), which is sold by Agfa (Orgacon) and Heraeus (Clevios).
The grids are highly refined near the walls and use the well known O grid strategy to well describe the vicinity of the hole injection
In order to improve the hole injection
, a highly conductive and transparent organic layer of Poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) is used.
Under the agreement, the companies will develop an advanced solution processible Hole Injection
Layer (HIL) technology for OLEDs.
Until recently, there were three models that give vastly different projections for oxide life: the thermochemical model, the anode hole injection
model, and the hydrogen release model.
