A solar cell includes a semiconductor substrate having a photoelectric converting portion, a first electrode formed on a first main surface of the semiconductor substrate, and a second electrode connected to the first electrode on the first main surface. The first electrode includes a plurality of first connecting portions to be connected to an interconnector and a first non-connecting portion not connected to an interconnector. The first non-connecting portion is arranged between first connecting portions to electrically connect the first connecting portions together. The first connecting portion and first non-connecting portion are coupled forming an angle larger than 90&#xb0; and smaller than 180&#xb0;. A solar cell string and a solar cell module employ the solar cells.

Solar cell, solar cell string and solar cell module

Disclosed is a method for manufacturing a solar cell module in which a wiring substrate having a base material and a wiring formed on the base material, and a plurality of solar cells electrically connected by being placed on the wiring of the wiring substrates are sealed with a sealant, including a first step of placing at least one of the solar cells on the wiring of the wiring substrate, and a second step of sealing the wiring substrate and the solar cells with the sealant, the method including the step of conducting an inspection of the solar cells after the first step and before the second step.

Method for manufacturing solar cell module

A light modulation circuit is provided which includes: a cold cathode tube; an inverter for turning the cold cathode tube on and off; and an adjustor for adjusting a current flowed through the cold cathode tube.

Light modulation circuit

A backlight device includes: a light source; a light-guiding plate; and a reflector. The light-guiding plate has a first principal surface and a second principal surface provided so as to face each other, and an end surface. The reflector is disposed so as to illuminate the end surface with light from the light source. The light-guiding plate has an output region on the first principal surface, for outputting light inputted from the end surface. An anti-reflection member is provided above the first principal surface in a region between the output region and the end surface.
