Abstract:
PURPOSE: A conductive reflection film and a manufacturing method thereof are provided to maintain high conductivity and high reflexibility by performing plasticity to a nano-particle sinter film after coating the film. CONSTITUTION: Sunlight is emitted from a board. The sunlight is reflected in a conductive reflection film (14). The most of the sunlight is returned to a photoelectric transformation layer (12). The conductive reflection film is formed on a transparent conductive film (13) of a thin film solar cell. The conductive reflection film is formed on the photoelectric transformation layer.
Abstract:
An object is to provide: a method for producing a dispersion solution of a metal nanoparticle, which enables to control the shape or particle size of the metal nanoparticle within a wide range; a dispersion solution of a metal nanoparticle, which has excellent dispersion stability; and a method for producing the dispersion solution. Another object is to provide: a dispersion solution of a metal nanoparticle, which has a volume resistivity of 2 to 6 × 10-6 Ω · cm which is a value useful for use as an electrically conductive material; and a method for producing the dispersion solution. Still another object is to provide a method for the synthesis of a metal nanoparticle, which can synthesize a metal nanoparticle from an insoluble metal salt without using no corrosive material and can produce a metal nanoparticle suitable as an electrically conductive material.
