SiOnyx produces polycrystalline silicon photovoltaic cells with 17% efficiency

SiOnyx revealed that its patented ultrafast laser texturing technology, BlackSilicon, has grown 0.3% more than the absolute efficiency of traditional industrial baseline solar cells. The company's 156mm polysilicon battery was produced by the company in cooperation with ISCKonstanz, and it is claimed that the average absolute efficiency exceeds 17%.

SiOnyx said that its Black Silicon technology can achieve such high efficiency because the silicon is thinner. The average efficiency of a 150-micron-thick polycrystalline silicon cell that is 20% thinner than an ordinary cell reaches 16.9%.

The battery is processed at the ISC Konstanz factory using standard emitters, screen-printed metal and aluminum back electric fields. Black Silicone texturing was then accomplished with the Coherent Aethon tool and Talisker picosecond laser.

Stephen Saylor, president and CEO of SiOnyx, stated: â€œThese results are a further validation of the Black Silicon process and its economic benefits for mainstream solar power. Now this technology is mature. Compared to the industry-standard heterostructure, Sinyx's unilateral The texture significantly reduces the surface reflectance and thus improves the battery performance. We have improved the infrared performance, making the Sinyx Black Silicon a very good complement to modern emitter technology."

The company further emphasized that its process results can significantly improve process consistency, and also pointed out that using the Black Silicon technology, the standard deviation of battery efficiency and current can reduce the two coefficients.

Grinding and polishing are the same mechanical movement, the principle is the same. But for surface quality, the surface finish of polishing is higher than that of grinding. In fact, polishing fluid can be said to be the last process of grinding, grinding and polishing can be realized on the same plane polishing machine at the same time. Grinding is divided into rough grinding, fine grinding, polishing is divided into rough throwing, fine throwing. Most of the time, we have three processes to process the surface quality of products: rough grinding, fine grinding, fine polishing. With these three processes, the workpiece surface flatness, parallelism, roughness is quite high. Some customers do not have such high accuracy requirements, especially roughness requirements are not so high, so they only use the first two processes, or the fine grinding process. Specific to see the quality of the workpiece surface itself, as well as customer requirements to achieve the quality.
