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： When a semiconductor layer formed via a separation layer on a substrate is supported by a support member and a pulling force is then exerted on the support member to mechanically break the separation layer to thereby form a thin-film semiconductor, the substrate is held by vacuum and/or electrostatic attachment and separation of the thin-film epitaxial layer is initiated from an area other than an edge of the substrate. This provides a method capable of obtaining the thin-film epitaxial layer with excellent characteristics in a good yield and permitting repetitive uses of the substrate, without inducing lifting of the substrate due to the separation force overcoming the attaching force of the substrate when producing a semiconductor base material and a solar cell.
