A method of manufacturing a solar cell including a silicon wafer is provided. In certain example instances, the method may include flattening fine roughness existing on a side face of a silicon block or a silicon stack used for manufacturing the silicon wafer for use in the solar cell.

Method of making solar cell

In a solar cell, at least one of reinforcing material and buffering material is provided at least partially on at least one of a back surface, a front surface and a side surface of the solar cell. With these reinforcing material and/or buffering material, occurrence of cell fracture due to load imposed by external force can be decreased.

A method of manufacturing a silicon wafer including the step of flattening fine roughness existing on a side face of a silicon block or a silicon stack used for manufacturing the silicon wafer.

Method of manufacturing silicon wafer

In a multi-wire saw, each wire guide has a cylindrical exterior configuration, and is composed of sectorial portions which are circumferentially separated and integrally formed in the axial direction thereof. Each sectorial portion provided in the wire guide has wire guiding grooves extending circumferentially on the peripheral surface thereof in parallel along the axial direction of the wire guide, and one group of sectorial portions which are located alternately to another group, is projected further out than the other group of sectorial portions, to form an envelope of a cylindrical shape as an exterior form.
