Photovoltaic crystalline silicon cell texturing equipment

Why is surface texturing important in solar cell fabrication?

Surface texturing for suppressing the reflection losses is the first and foremost step in the solar cell fabrication process. Over the years, multi-crystalline silicon (mc-Si) wafer solar cells dominated the PV market due to their cost-effectiveness.

Who are the authors of a review article on crystalline silicon solar cells?

Authors are thankful to Prof. K. L. Narasimhan, Prof. B. M. Arora, Mr. Sandeep Kumbhar, Mr. Almoazzam Khan and other students and staff members of the “Crystalline Silicon Solar Cells” group of NCPRE for the helpful discussions and guidance in preparing the review article.

Why is alkaline texturing important in solar cells?

Texturing the surface of crystalline silicon wafers is a very important step in the production of high-efficiency solar cells. Alkaline texturing creates pyramids on the silicon surface, lowering surface reflectivity and improving light trapping in solar cells.

How does silicon surface texturing work in solar cells?

Silicon surface texturing is an effective way of light trapping for solar cells application [9, 12]. Light trapping is typically achieved by altering the way the light travels by making it incident on an angled surface in the solar cell.

Which material is used for commercial solar cells?

Silicon (Si) which is an important material of the microelectronics industry has also been the widely used bulk material of solar cells since the 1950s with a market share of >90% [ 2 ]. The chapter will introduce the typical steps for manufacturing commercial silicon solar cells.

What is n-type emitter of crystalline p-type silicon solar cells?

The n-type emitter of the crystalline p-type silicon solar cells is formed by phosphorus (P) diffusion. In the diffusion process, the Si wafers are sent in a furnace and exposed at 800–900°C to phosphoryl chloride (POCl 3) and O 2 which results in PSG deposition on the Si wafer surfaces.
