This solar cell module comprises: a base member curved in the vertical direction and the horizontal direction; a plurality of solar cells disposed on the base member; first wiring members connecting adjacent solar cells to one another in the vertical direction and forming a plurality of strings; and second wiring members connected to the first wiring members that extend out in the vertical direction from the top of the solar cells located at an end of the columns of the strings. The interval between the at least some of the second wiring members and the solar cells of the strings connected to those wiring members is narrower toward the end portions in the horizontal direction of the string group than toward the central portion in the horizontal direction.

Solar cell module

This solar module has: a base member that is curved in the vertical direction and the horizontal direction; strings each constituted from a plurality of solar cells and first wiring members connecting adjacent solar cells in the vertical direction, wherein a plurality of the strings are arranged side by side on the base member; and a string group constituted from a plurality of the strings and second wiring members, which are disposed at both sides in the vertical direction of the strings and connected to the first wiring members, thereby connecting adjacent strings to one another in the horizontal direction. The string group is divided into at least two blocks that are side by side in the vertical direction. Second wiring members are disposed adjacent in the horizontal direction, or second wiring members are disposed adjacent in the vertical direction between the blocks, and are secured to one another.

Solar cell module and solar cell module production method

A solar battery module is provided with a plurality of solar cells, a wiring material for connecting adjacent solar cells in the longitudinal directors to form strings, and a reflective body disposed on the rear-surface side of the solar cells, said body reflecting at least some incident light toward the solar cells. In the solar battery module, the strings are multiply disposed in the horizontal direction to constitute string groups, intervals Dbetween adjacent strings being formed wider in the longitudinal center section of the string groups than in the longitudinal end sections.

In this method for producing a photoelectric conversion device: an i-type non-crystalline layer and an n-type non-crystalline layer comprising a non-crystalline semiconductor film are formed on the light-receiving surface of a semiconductor substrate; an i-type non-crystalline layer and an n-type non-crystalline layer comprising a non-crystalline semiconductor film are formed on the back surface of the semiconductor substrate; a protective layer is formed on the n-type non-crystalline layer; an insulating layer is formed on the n-type non-crystalline layer; and in the state where the top of the n-type non-crystalline layer is covered by the protective layer, patterning is performed by eliminating a portion of the i-type non-crystalline layer, the n-type non-crystalline layer, and the insulating layer.

An air conditioner comprising a casing, an air flow passage extending from an air inlet at the upper side of the casing to an air outlet at the lower side of the casing. A cross flow fan is provided within the casing along with a heat exchanger composed by connecting fins through which air is allowed to pass to the outer surface of the heat transfer tube along the lengthwise direction thereof. The heat transfer tube is branched into a plurality of passes in the heat exchanger. The present invention is characterized in that the heat transfer tube is disposed in a direction crossing the axial direction of the cross flow fan. Even if drift of flowing air is caused by the cross flow fan, distribution in the air flow speed and distribution of heat exchanger can be made equal and heat exchanging capacity of high level can be obtained, without causing the trouble of condensed water from the heat exchanger falling into the air flow passage.
