1. Field
Example embodiments relate to a transmissive electrode, a photoelectric device and/or an image sensor including the same.
2. Description of the Related Art
A photoelectric device may convert light into an electrical signal. Examples of photoelectric devices include a photodiode, a phototransistor, and the like. A photoelectric device may be applied to an image sensor, a solar cell, an organic light emitting device, and the like.
An image sensor including a photodiode may have higher resolution and accordingly a smaller pixel. At present, a silicon photodiode may be used. Silicon photodiodes may have less sensitivity when the pixel is smaller due to a smaller absorption area. Accordingly, an organic material that is capable of replacing silicon has been researched.
Organic materials may have a high extinction coefficient and may selectively absorb light in a particular wavelength region depending on a molecular structure, and thus may simultaneously replace a photodiode and a color filter and improve sensitivity and contribute to high integration.
In order to realize a photodiode having a higher photoelectric conversion efficiency based on the organic material, it is desirable to improve characteristics of a transmissive electrode.
