HPBC solar panel

 Take LONGi Green Energy's HPBC cells as an example, they have the following characteristics:

- Front grid-free design: It can significantly enhance the absorption of light.

- Multi-layer passivation technology: It can effectively reduce the impurity load during the photoelectric conversion process and greatly increase the conversion efficiency.

- All-back positive and negative electrode connection technology: It ensures the stable current output of the cells.

- High efficiency: The standard version's mass production efficiency exceeds 25%, and the pro version with hydrogen passivation technology has an efficiency of over 25.3%.

- Good power generation performance: Optimizations have been made in aspects such as light absorption, performance at high temperatures, low irradiation response, and power attenuation. According to the simulation results of power generation in typical global regions, its average gain is 10% compared to PERC products.

- High reliability: For example, the all-back welding technology is adopted, and the welding method is more stable and reliable, which can effectively improve the battery's resistance to lithium electricity and enhance the reliability of the product.

LONGi Green Energy's HPBC technology and related components are mainly targeted at the distributed photovoltaic market and can be installed on the rooftops of households and enterprises.

On October 25, 2023, the return and receiving ceremony of LONGi's HPBC solar cells carried by Shenzhou-15 was held in Jiuquan City, Gansu Province. This battery product has undergone a half-year verification in the space environment, aiming to withstand the harsh space environment tests and promote continuous upgrading of product quality. Currently, LONGi Green Energy's HPBC cells and components have been put into production, and the production capacity has entered a state of full production operation.

The specific performance and characteristics of HPBC solar panels may vary depending on the production processes and technical levels of different manufacturers. In practical applications, factors such as efficiency, reliability, and cost all need to be comprehensively considered.
