DSSC (Solar Cell)
The type of next generation Solar Cell
DSSC consists of crystallization system, inorganic and organic thin film systems according to the structures and elements of solar cells.
Crystalline System
Good for space limited house as it has high efficiency in transforming ratio of thin file system.
Thin Film System
Low System Cost, and applicable to power generation plant that allow to utilize broad space.
Compound system
Good in a-Si ratio efficiency, but hard to make it bigger (CIGS)
Organic system
Easy to apply to construction material as it has good decorative feature.

The fundamentals of next generation Solar Cell
The electron occurred by the principle that an electron is occurred when light induction dyes absorbs luminous energy, diffuses through porous semiconductor electrode, contact to conductive panel, and transmits election to molecule of dyes where a pair of oxidation-deoxidation ion included in electrolyte is in the ground state.
Reproducibility of various color impression as absorption layer for solar light is dyes.
Securable Transparency by controlling thickness of Nano-particle(TiO2)
