Abstract: In order to provide an electro-conductive paste bringing no increase of the contact resistance for forming an electrode of a solar cell device, the electro-conductive paste is characterized by containing an electro-conductive particle, an organic binder, a solvent, a glass frit, and an organic compound including alkaline earth metal, a metal with a low melting point or a compound affiliated with a metal with a low melting point.
Abstract: After fluid material containing transparent conducting fine particles is coated on a substrate to form a coating film, and the transparent conducting fine particles are sintered by irradiating an electromagnetic wave after pressure is added to this coating film. For example, the pressure is added to the coating film so that density of the coating film becomes 3.0 g/cm3 or more. Besides, for example, the pressure is added to a surface of the coating film by means of a roll press. Besides, for example, a line pressure of the roll press is set to be 200 kg/cm or more. Besides, for example, the irradiated electromagnetic wave is a microwave of 1 GHz to 1 THz.
Abstract: The change in resistance over time of a low-resistance acicular ITO powder is reduced, and the stability of the ITO powder in ambient air is improved. Tin-containing indium hydroxide baked in an atmosphere of an inert gas and reducing gas is processed for a predetermined time under a water-containing atmosphere of inert gas and/or reducing gas at a temperature of 0° C. or greater and 100° C. or less, and is then exposed to air.
