Solar PV equipment manufacturer LAPLACE calls itself a pioneer in the space in terms of TOPCon cell technology for mass production. LAPLACE’s Director of Technology, International Business Unit, Josua Stückelberger, at the TaiyangNews High Efficiency Solar Technologies 2024 conference claimed that the company’s equipment and process have led to the highest TOPCon solar cell efficiency of 26.89% at the R&D level.
For the new mainstream technology TOPCon cell production, LAPLACE supplies a variety of equipment barring wet tools and metallization. The introduction of improvements such as double-loading facilitates higher throughput and reduced costs. Its proprietary coated quartz tubes extend lifetimes by 6 to 9 months, thus bringing down operational costs, added Stückelberger.
As it diversifies into BC technology, Stückelberger shared that LAPLACE is ready with solutions to help its TOPCon clients integrate this and other next-generation technologies as well. Implementation for XBC requires the use of LPCVD for the deposition of both the tunnel SiOx and polysilicon layers which its equipment is fully compatible to accomplish. Some of this equipment is already delivered and operating successfully, he added. In addition, the company is now expanding its product offerings by including laser tools in its portfolio to offer a complete solution for XBC.
Almost all the tools from its TOPCon technology can be reused in the XBC process after some rearranging and equipment upgrades, thus ensuring cost control during the transition.
