Recently, Taizhou Zhonglai Optoelectronics Technology Co., Ltd. received a report from the National Center for Photovoltaic Product Quality Supervision and Inspection (CPVT). The report shows that the conversion efficiency of the N-type IBC battery of Zhonglai Optoelectronics M2 size is 22.22%, and the IBC battery can be mass-produced. Technology is in the leading position in the industry.
The double-sided battery of the N-type IBC structure is the battery structure with the highest conversion efficiency in the N-type battery. The front of the battery is not covered by the grid lines. The optical trapping effect and the surface passivation of the front surface and the metallization of the battery are respectively on the two surfaces of the battery. Therefore, the mutual restriction between them cannot be considered, and the IBC battery is greatly expanded. Optimum space for optical and electrical performance, battery conversion efficiency has also been greatly improved.
Coal mine rock tunnel drilling and loading unit( referred to as" Drill Loader") is an efficient continuous operation equipment that integrates two functions of rock drilling and loading. Mainly used for excavation operations in mine rock tunnels, diversion tunnels and other engineering tunnels. Its application increases the speed of excavation, reduces the labor intensity of work, improves the safety of excavation construction operations, and well realizes the mechanized operation requirements of rapid excavation of rock tunnels. At the same time, it solves the problem of not driving various equipment in small and medium roadways. The two drill arms of the drilling unit can simultaneously blast holes on the working face of the roadway, or simultaneously blast and top the bolt holes. The backhoe mechanism picks up the rock from a distance and sends it to the scraper conveyor. The scraper conveyor unloads the rock from the tail into the mine cart or belt conveyor. The bucket can also be used to clean the working surface. The breaker is integrated on the boom, which does not need to be disassembled during use. When large rocks are encountered, the breaker on the boom can be used to break.
