Meyer Burger solar modules combine the most advanced technologies in solar cell manufacturing and connection. As a result, the highest efficiencies of all commercially used solar modules are achieved.
HJT solar cells connect two photovoltaic worlds with each other and thus use the advantages of both crystalline solar cell technology and thin-film photovoltaics. For the production of the electrical structures of heterojunction cells, thin layers of amorphous silicon on both sides of a monocrystalline silicon wafer as well as transparent, conductive oxide layers are applied.
While the crystalline silicon structures generally enable higher efficiencies, the amorphous silicon ensures a better light yield - even in diffuse light. In addition, heterojunction cells have a significantly lower temperature coefficient than conventional silicon solar cells, which means that their performance remains stable even at high temperatures.
SmartWire Connection Technology (SWCT)
SWCTTM is an exclusive patented Meyer Burger technology for connecting solar cells with each other. A wire foil replaces the usual soldered bus bars. The wires form a dense contact matrix, which leads to a significantly higher power gain. Solar cells with SmartWire connection are less susceptible to microcracks and have a better current flow due to reduced resistance. Furthermore, the wires reduce shading on the cell surface, as is the case with the significantly wider bus bars. This leads to a significantly better light yield.
The amorphous silicon layers, which give the heterojunction solar cells their outstanding properties, can easily be destroyed at excessively high temperatures in the production process. SmartWire is therefore the optimal connection technology and is more suitable for highly efficient heterojunction solar cells than the hot busbar soldering processes.
