An impeller of a centrifugal fan having fifty or more blades of not larger than 250 mm in outer diameter which has a casing and a multi-blade impeller rotatably supported in the casing, wherein a centrifugal force is applied on air entered into an inlet formed on the casing when the impeller is rotated, and an air of high pressure is taken out through an outlet formed on a portion of the casing. An outer peripheral surface of the impeller is inclined or curved so as to have an inlet side large diameter portion and a blade holding base side small diameter portion, or is stepped so as to have an inlet side cylindrical outer peripheral surface of large diameter and a blade holding base side cylindrical outer peripheral surface of small diameter connected to the inlet side cylindrical outer peripheral surface. The inlet side cylindrical outer peripheral surface and the blade holding base side cylindrical outer peripheral surface are substantially the same height.

The surface of an amorphous silicon film formed on a glass substrate is cleaned by hydrofluoric acid in a spin clean unit. The glass substrate is conveyed to a waiting unit where the glass substrate is made to wait for about 15 minutes. Active fluoride adhered on the amorphous silicon film is sublimated. The glass substrate in which the active fluoride is sublimated is conveyed into a laser annealing device where the amorphous silicon film is excimer laser annealed to reform the amorphous silicon film into a polysilicon film. The residuals of the charges in the polysilicon film generated by excimer laser annealing the surface of the amorphous silicon film with the active fluoride adhered to the surface of the amorphous silicon film can be prevented. A thin film transistor having desired TFT characteristics can be manufactured.

摘要:
It is aimed to provide a solar cell element and a solar cell module capable of reducing an output drop in a case where a crack occurs in the solar cell element. In order to achieve this object, the solar cell element includes a substrate body including a photoelectric conversion part, a plurality of first electrodes located at intervals on one main surface of the substrate body, and a crack guiding part located in a region positioned between a pair of adjacent first electrodes among the plurality of first electrodes when the substrate body is viewed or viewed through in plan view from the one main surface side and configured to guide a position of a crack occurring in the substrate body upon application of a load to the substrate body.

A pair of sealing films is produced for sealing a seal target member configured to be interposed between the sealing films. The pair of sealing films are characterized by including ethylene-vinyl acetate copolymer, the first sealing film including magnesium hydroxide in an amount of 0.2 parts by weight or less based on 100 parts by weight of the ethylene-vinyl acetate copolymer, and the second sealing film including magnesium hydroxide in an amount of 0.01 parts by weight or more based on 100 parts by weight of the ethylene-vinyl acetate copolymer. Moreover, a solar battery including the pair of sealing films is characterized by the structure including a light-receipt side transparent protection member; a first sealing film including ethylene-vinyl acetate copolymer and covering the light-receipt side transparent protection member; a back side protection member; a second sealing film including ethylene-vinyl acetate copolymer and covering the back side protection member; and solar cells provided between the first and the second sealing films. The first sealing film includes magnesium hydroxide in an amount of 0.2 parts by weight or less, based on 100 parts by weight of the ethylene-vinyl acetate copolymer, and the second sealing film includes magnesium hydroxide in an amount of 0.01 parts by weight or more, based on 100 parts by weight of the ethylene-vinyl acetate copolymer.
