    摘要： A solar cell module comprises a plurality of unit cells connected in series, each of the unit cells comprising in this order an electrode, a first semiconductor layer having a first conductivity type and a second semiconductor layer having a second conductivity type. The electrode has a region not covered with the first semiconductor layer. The second semiconductor layer has a main region and a subregion which are separated by a groove. The main region of the second semiconductor layer in one unit cell is electrically connected to the region of the electrode not covered with the first semiconductor layer in another unit cell adjacent to the one unit cell. The region of the electrode not covered with the first semiconductor layer in the one unit cell is electrically connected to the subregion of the second semiconductor layer in the another unit cell. With this structure it is possible to simplify the formation of a bypass diode invention therefore provide solar cell module with high reliability at a low cost.

    摘要： A method for manufacturing a thin-film crystalline solar cell includes the steps of (i) forming a porous layer including a large number of fine pores in a surface portion of a crystalline substrate, (ii) transforming a part of the porous layer including the surface thereof into a smooth layer which does not include fine pores by providing the porous layer with excitation energy, and (iii) peeling the smooth layer from the substrate. The excitation energy is provided, for example, by performing heat treatment in a hydrogen atmosphere, irradiating with light having a wavelength equal to or less than 600 nm, or irradiating with an electron beam. It is thereby possible to form a thin-film crystalline semiconductor layer on an inexpensive and flexible substrate by simple processes.

    摘要： A process for producing a semiconductor substrate is provided which comprises a first step of anodizing a surface of a first substrate to form a porous layer on the surface, a second step of simultaneously forming a semiconductor layer on the surface of the porous layer and a semiconductor layer on a surface of the first substrate on its side opposite to the porous layer side, a third step of bonding the surface of the semiconductor layer formed on the surface of the porous layer to a surface of a second substrate, and a fourth step of separating the first substrate and the second substrate at the part of the porous layer to transfer to the second substrate the semiconductor layer formed on the surface of the porous layer, thereby providing the semiconductor layer on the surface of the second substrate. This makes it possible to produce semiconductor substrates at a low cost while making good use of expensive substrate materials.
