The thin crystalline silicon solar cell (60–90 μm) is prone to crack due to surface texture when it is under bending. Here we investigated the effect of pyramid size on optical reflectivity and mechanical properties of silicon wafers. We find that smaller and uniform pyramids are beneficial for obtaining efficient and flexible silicon solar cells.
To validate the industrial compatibility of TSRR structure, we further prepared textured TSRR wafers and performed some key manufacturing processes for mass production of silicon solar cells based on 182 × 182 mm 2 pseudo-square wafers with an original thickness of 150 μm which are generally used in industry.
This fact enabled us to improve the flexibility of silicon wafers by blunting the pyramidal structure in the marginal regions. This edge-blunting technique enables commercial production of large-scale (>240 cm 2), high-efficiency (>24%) silicon solar cells that can be rolled similarly to a sheet of paper.
Next, we fabricated the foldable c-Si wafers into solar cells. The most widely used industrial silicon solar cells include passivated emitter and rear cells 18, tunnelling oxide passivated contact 19 solar cells and amorphous–crystalline silicon heterojunction 20 (SHJ) solar cells.
