The combination of two revolutionary cell and module concepts: heterojunction solar cells and Smart Wire Connection Technology module technology are leading technologies for the next generation of PV modules. These two concepts combine high module power (>300 Wp based on 60 cells module) and a cell production cost as low as 13 c$/Wp.
Therefore, the heterojunction cell module has higher power generation. The new busbar-free heterojunction cell technology, coupled with dense ultra-fine round low-temperature lead-free welding wire, can achieve silver saving, less shielding and shorter transmission distance.
The metallization cost of heterojunction solar cells production has been strongly reduced by adapting the cell interconnection in modules from three busbars to the SmartWire Connection Technology (SWCT) .
Introduction Crystalline silicon solar cells based on HeteroJunction Technology (HJT) are the most promising candidate for competitive high-efficiency silicon solar cells.
Cando Solar heterojunction cell module, for the first time in the industry, adopts the lowest carbon photovoltaic product in the dual-carbon era. 3. System design can have a smaller area while maintaining the same power generation. Cando Solar version 40 the installation requirements to the greatest extent.
Outstanding heterojunction solar cell efficiency > 25.6% was announced this year by Panasonic and during the last two years, many institutes and companies (Meyer Burger , CIC , EPFL , CEA-INES …) have presented impressive cell efficiency ramp-ups (up to 22%) in a very short period of time thanks to this technology.
