摘要:
A surface electrode (5) is installed on the light receiving surface of a solar cell element, the surface electrode (5) comprises three bus bar electrodes (5a) for extracting light-produced at the solar cell element to the outside and collecting finger electrodes (5b) connected to these bus bar electrodes (5a), and the bus bar electrodes (5a) are not less than 0.5 mm and not more than 2 mm in width and the finger electrodes (5b) are not less than 0.05 mm and not more than 0.1 mm in width. A high-efficient solar cell module can be obtained with substantially lowered resistance by increasing the number of bus bar electrode (5a) and thereby decreasing the lengths of the finger electrodes (5b).

摘要:
A solar cell module includes a base body, a plurality of solar cell elements arranged at intervals over the base body, a resin layer disposed on the solar cell elements and comprising a plurality of recesses on its surface facing opposite to the solar cell elements, and a protective sheet disposed on the resin layer. The protective sheet comprises a plurality of protrusions which correspond to the recesses of the resin layer and which are in contact with the recesses. The height of first protrusion at a location corresponding to the interval between the solar cell elements among the plurality of protrusions is higher than the height of second protrusion at a location corresponding to the solar cell element among the plurality of protrusions. The interval between adjacent ones of the second protrusions in a portion corresponding to an end portion of the base body in longer than the interval between adjacent ones of the second protrusions in a portion corresponding to a central portion of the base body.

Superior yield is achieved by eliminating the occurrence of cracks after connecting together solar cells by soldering on connecting conductors so as to provide highly reliable connecting conductors and solar cell modules. The solar cell modules have solar cells formed with electrodes and ribbon-shaped connecting conductors connecting with the electrodes using solder. The plane shape of at least one end of the connecting conductors is provided with a plurality of angled sections with obtuse angles.

The present invention provides an inter-bus-bar built-in capacitor capable of reducing the size of a capacitor used in an inverter or the like or downsizing the capacitor, and provides power equipment as well as a power converting apparatus. The inter-bus-bar built-in capacitor is provided between a pair of opposing bus bars and includes a high-dielectric-constant material which has a relative dielectric constant of at least 50 when a voltage of 1,000 V is applied at a temperature of 25° C. Thus, it is possible to provide the inter-bus-bar built-in capacitor capable of reducing the size of a capacitor used in an inverter or the like or downsizing the capacitor and provide the power equipment as well as the power converting apparatus.
摘要:
Disclosed is an inorganic polysilazane that undergoes less shrinkage during a calcination step in an oxidizing agent such as water vapor and is less prone to allow a silica film to suffer from the formation of cracks or peel off from a semiconductor substrate, and a silica film-forming coating liquid containing the inorganic polysilazane, and also provides an inorganic polysilazane and a silica film-forming coating liquid containing the same. The value of A/(B+C) is 0.9-1.5 and the value of (A+B)/C is 4.2-50. A=peak area within the range of from 4.75 ppm to less than 5.4 ppm. B=peak area within the range of from 4.5 ppm to less than 4.75 ppm. Peak area within the range of from 4.2 ppm to less than 4.5 ppm is represented by C in a 1H-NMR spectrum; and the polystyrene-equivalent mass average molecular weight is 2000 to 20000.
