The new Sunweb solar cell developed and tested by the R&D division of Solland Solar in collaboration with ECN (Energy research Centre of the Netherlands) is claiming to offer nine percent higher output.
Netherlands' largest producer of solar cells, Solland Solar, says that by concentrating the generated energy to the back of the cell, Sunweb can offer a two percent higher output per cell. Processed and connected in a solar module, the output increases to nine percent.
The Sunweb cell transfers the collected energy at the front of the cell using MWT (Metal Wrap Through) method through to the back of the cell.
Removing the 'bus bars' from the front of the cell gives the Sunweb cell a larger surface area available for collecting (sun)light and converting it to electricity. Whereas the output of a solar module with a traditional cell is around 13.5 percent, the Sunweb cell increases this efficiency to about 15 percent.
Solland is currently working with third parties on the development of a special back-sheet foil to connect the Sunweb cells at the back and enable further automation of the production process, saving time and cost in the manufacturing of solar modules.
