Organic solar cell
a photovoltaic cell that uses organic electronics like conductive organic polymers or small organic molecules for light absorption and charge transport
Basic principle of solar cell
When light is illuminated at cell, the photons are absorbed in the organic layers.
The excitons diffuse to interface between donor and acceptor.
The excitons are separated by electron
Principle of cvd
High purity and quality deposition
Good economy and process control
A great variety of chemical compositions
High step coverage
Selective deposition
AdvantageS of CVD
Classification of CVD
Thermal(conventional) CVD
- Operating Temp. : 800 1200 ℃
- Mass Products
- High Purity Thin Film
- influenced by various factors
Metal-Organic CVD(MOCVD)
- Metal-Organic compoun
it is established to carry out public mission and services. In order to do these duties, a government corporation participates in activities or provides services efficiently as private enterprises do. In other words, a government corporation is granted increased operating flexibility to best ensure its success, while retaining principles of public accountability and fundamental public policy.

First, Substrate is consists of a plastic or glass, a portion of the OLED is supportive.Anode is a role that make electron holes when current flows by removing electron. And the upper Conducting Layer is the place that Electron Holes is being created.Emissive Layer is the place accepting an electron from Cathode and produce light.
Emissive layer and conducting layer are called organic layer beca
