In the evolution of single‐crystal silicon solar cells, crystallographic texturing of the cell surface using anisotropic etches was an important step in improving cell performance. Unfortunately, this technique is ineffective for polycrystalline silicon solar cells due to generally unfavorable grain orientation. This limitation has been overcome by employing a new laser texturing technique

6 FAQs about [Texturing of polycrystalline silicon solar cells]
What is the best texturing solution for monocrystalline Si?
For mono-crystalline Si, the preferred texturing solution is alkaline-based. If an acid texturing bath is used, a KOH or NaOH bath is used after it to remove the porous that silicon remains on the surface.
Does a single emitter photovoltaic (PV) surface texture affect doping uniformity?
Results show that the initial texturing topology and reflectivity is not affected by the subsequent rinses and the doping uniformity is also the same as with the standard chemicals. Texturing of the surface is the first step of the single emitter photovoltaic (PV) manufacturing process for both mono- and multi-crystalline silicon wafers.
Are crystalline silicon solar cells a good investment?
In the meantime, crystalline silicon (c-Si) solar cells are also promising because of their high conversion efficiency, high operating stability, environmental-friendly process and flexibility when they are thin enough.
Why are small pyramids important for flexible crystalline silicon solar cells?
For flexible crystalline silicon solar cells, smaller pyramids can make the silicon wafers more flexible, and a more uniform distribution of pyramid size is a better light trapping structure that can achieve higher power conversion efficiency. So, obtaining small and uniform pyramids is important for flexible and efficient silicon solar cells.
What is a silicon heterojunction solar cell?
Among c-Si solar cells, Silicon Heterojunction (SHJ) solar cells can achieve the perfect combination of high efficiency and low cost thanks to the superior passivation effect by amorphous silicon passivation layer , .
How does the texturing process work?
The texturing process roughens the surface and reduces the reflection of the silicon surface by etching along crystal planes and grain boundaries to increase the surface area to provide more light trapping.
