<p>PROBLEM TO BE SOLVED: To provide a solar cell unit, capable of protecting solar cells against deterioration, superior in reliability, durability, and mass productivity and a method of manufacturing it. SOLUTION: A solar cell unit is equipped with a board 1, where electrodes 12a and 12b are formed, a solar cell 10 jointed to the electrodes 12a and 12b formed on the board 1 so as to make the electrodes partially exposed, electrodes 11a and 11b jointed to a part of the electrodes formed on the board, a heat spreader 13 which is jointed to the board to dissipate heat, and a secondary condensing lens 14 jointed on the solar cell for guiding incident light to the solar cell. The connection of a part of the electrode formed on the board to the solar cell and the other connections of the other part of the electrode formed on the board with the electrode lead are made in batch, and the connection of the board with the heat spreader which dissipates heat and the connection of the solar cell with the secondary condensing lens, which guides incident light to the solar cell, are collectively made for assembly.</p> |
