Leadmicro’s innovative solutions for high efficiency c-Si solar cell productions


Driven by increasing market demand for high efficiency, low-cost c-Si solar cells, Leadmicro delivers high-performance production solutions for passivation and texturing of advanced solar cell structures for both multi- and mono-crystalline silicon wafers. Compared to traditional BSF cell structure, Leadmicro photovoltaic technology can improve the solar cell efficiency of more than 1 % when a c-Si based high efficiency solar cell production line is new built, converted or upgraded into a PERC line. Combined with proprietary, production proven, and fully automated advanced load/unload wafer handling systems, Leadmicro provides a complete solution for high efficiency solar cell manufacturing. Leadmicro’s photovoltaic products are the most advanced systems for PERC/PERL/PERT cell production with the lowest Cost-of-Ownership available in the market.




Kuafu Series ALD Al2O3 Passivation System

Modular process system with dedicated load/unload wafer handling automation, KF4000 features high loading volume with throughput of 3600 w/h and a long maintenance time of >14 days. The unique chemical delivery and distribution system significantly reduces the TMA usage while maintain high deposition performances for production thus makes it the market lowest Cost-of-Ownership system for high volume production. Available for both single and double side coating, the KF series is the best choice for PERC/PERL/PERT solar cell production.
