An Analysis of Low-Pressure High-Frequency Plasma Chemical Vapor Deposition System for Flexible Solar Cell Characteristics

Abstract:

The flexible dye-sensitized solar cells have a need to improve adhesive property in each layer in order to increase efficiency of this solar cell. Flexible surface with Polyethylene naphthalate (PEN) were modified by using surface treatment from developed the low-pressure high-frequency Plasma Chemical Vapor Deposition system in order to improve adhesive characteristic. The oxygen plasma treatment can improve adhesive property of Polyethylene naphthalate (PEN) films and also cleaning surface. We were using the mixture of Ar and O₂ gas for plasma treatment with oxygen gas flow rate from 0.1 L/min. to 0.5 L/min. while Ar gas flow rate was set at 10 L/min. and 5 minute for treatment time. The results indicate that using low-pressure high-frequency Plasma Chemical Vapor Deposition system can be possible improvement adhesive characteristic of PEN films with radical increased on films.
