Abstract
A solar battery module according to the present invention includes interconnectors for series-connecting a plurality of solar battery cells, and one or more bypass diodes which allow output currents of the cells to be bypassed with respect to one or more cells, wherein each of those diodes is a chip shaped thin diode and is attached on an electrode or a cell or between interconnectors.
Claims15
A solar battery module, comprising:
- a plurality of solar battery cells arranged in a linear array;
- each said cell including a front electrode and a back electrode, each front electrode including a plurality of parallel conductors located on a light receiving surface of each cell and extending in a direction along the length of said linear array;
- said cells being electrically series-connected by interconnectors connected to each of said electrodes and extending in a direction along the length of said linear array;
- and
- each said cell including a bypass diode which allows output currents of said solar battery cells to be bypassed with respect to one of said solar battery cells, wherein
- each said bypass diode is a chip shaped thin diode and is attached to one of said parallel conductors of a front electrode of a cell and connected to an adjacent cell front electrode by an interconnector extending in a direction along the length of said linear array.

A solar battery module comprising:
- a plurality of solar battery cells which are electrically series-connected and arranged in a matrix array of rows and columns;
- and
- each said cell including a front electrode and a back electrode, each front electrode including a plurality of parallel conductors located on a light receiving surface of each cell and extending in a direction along the length of said linear array;
- at least one bypass diode for each two rows of the matrix array, which allows output currents of said solar battery cells of the respective two rows to be bypassed with respect to said plurality of solar battery cells, wherein
- solar battery cells on opposite ends of each said two rows of said plurality of series-connected solar battery cells to be bypassed are arranged in close proximity to each other, and
- said bypass diode is a chip shaped thin diode and is attached on a front electrode of one of said opposite end cells of each said two rows.

A solar battery module, comprising:
- a plurality of solar battery cells electrically connected in series by roof-tile-stacking, each said cell including a front electrode on a light receiving surface and a back electrode;
- and
- at least one bypass diode which allows output currents of said solar battery cells to be bypassed with respect to at least one of said solar battery cells, wherein
- said bypass diode is a chip shaped thin diode and is attached on a back electrode of said solar battery cell and wherein
- said solar battery cell is provided with an interconnector extending on its back electrode and being attached to one end of said bypass diode, the other end of which is attached to the back electrode of an adjacent solar battery cell, the extending portion of said interconnector serving to minimize a decrease of the output when said solar battery cell is cracked.
