摘要： A solar battery cell, solar battery module, and solar battery module group achieving high product value by enabling the display of surface patterns without reducing the power generating efficiency of the solar battery cells are provided. The direction and/or reflectance of reflected light incident to the surface of the solar battery cell are varied by controlling the distribution of the rough surface structure imparted to the solar battery cell surface. The direction or reflectance of reflected light incident to the surface of the solar battery cell is changed in part depending upon the part of the semiconductor solar battery cell surface to which the light is incident. Semiconductor solar battery cells with high product value can therefore be achieved because patterns with strong visual impact can be displayed and easily recognized without reducing the power generation efficiency of the solar battery cell.

摘要： A process of forming electrodes is simplified during modularizing of a solar battery. According to the manufacturing method and the manufacturing apparatus, a thin solar battery is manufactured at a reduced cost and with a better yield. Using a robot which includes a suction chip which can handle a semiconductor film 2 without any damage which is separated from a particular substrate 1, the semiconductor films 2 are each accurately placed through a transparent resin 3 onto a glass substrate 7 which serves as a window of a solar battery, and p-type and n-type electrodes are printed at a time on the semiconductor films 2 which are arranged. Further, since a monolithic tab electrode is soldered to connect the electrodes, the manufacturing processes of the solar battery are simplified.

摘要： In a method for fabricating a thin film solar cell, a thin semiconductor film serving as a power generating layer is formed on a substrate via an intermediate layer, a plurality of holes are formed penetrating through the thin semiconductor film and reaching the intermediate layer, and the intermediate layer is etched away through the through-holes, separating the thin semiconductor film from the substrate with high-efficiency. Since stress is hardly applied to the thin semiconductor film during the separation process, cracking and breaking of the semiconductor film is avoided. Further, since the surface of the substrate is maintained in good condition, the substrate can be reused, resulting in a reduction in the production cost.

摘要： A water-repellent layer is formed on a light-receiving surface of a solar battery prior to the formation of a coated-film electrode. The coated-film electrode is formed by screen-printing a coating solution on the water-repellent layer. The coating solution is restricted from spreading on the surface of the water-repellent layer and a narrow ridge-shaped coated-film electrode is formed. Thus, the front electrode is smaller in width and larger in height, so received light loss and transmission loss are decreased.

摘要： A thin-film solar cell includes a thin active layer of high purity material having opposed front and rear surfaces for light-to-electricity conversion, a structure for supporting the thin active layer, and a rear electrode in contact with the rear surface of the active layer. The supporting structure includes a supporting substrate of a low purity material having opposed front and rear surfaces, on the front surface of which the rear surface of the active layer is disposed, and an insulating barrier layer interposed between the front surface of the supporting substrate and the rear surface of the active layer. The barrier layer prevents impurities in the supporting substrate from diffusing into the active layer. Since the supporting substrate comprises a low purity material, the quantity of the expensive high purity material can be reduced by reducing the thickness of the active layer, resulting in low production costs. Since the supporting substrate is present on the rear surface of the active layer, a surface electrode disposed on the front surface of the active layer is exposed. Therefore, when a solar cell module is fabricated using a plurality of the solar cells, a wire bonding process for connecting adjacent solar cells is easily carried out.
