CRYSTALLINE SILICON WAFER, CRYSTALLINE SILICON SOLAR CELL, METHOD FOR MANUFACTURING CRYSTALLINE SILICON WAFER AND METHOD FOR MANUFACTURING CRYSTALLINE SILICON SOLAR CELL

摘要

Disclosed is a crystalline silicon wafer (1) whose surface is provided with recesses and projections. The recesses and projections include first recesses and projections (2), and second recesses and projections (3) which are smaller than the first recesses and projections (2). Also disclosed are a crystalline silicon solar cell (11) using such a crystalline silicon wafer (1), a method for manufacturing such a crystalline silicon wafer (1), and a method for manufacturing such a crystalline silicon solar cell (11).
