Multicrystalline Solar Cells from Solland Solar

Solland Solar supplies three types of crystalline solar cells namely standard cells, back-contact cells and B2B cells. The standard cells with H-pattern front grid are multicrystalline solar cells. They are available in 156 x 156mm size.

Surface texturisation is done to the solar cells to give a dark homogenous appearance. The electrical performance of every solar cell is tested and sorted according to narrow power classes. The solar cell testing equipment is standardized on a normal basis to comply with the standards of IEC 60904-9. The standard cells undergo visual inspection for aesthetic and mechanical faults. Parallel resistance and hot spot resistance tests are carried out for a low light behavior.

The standard cells are made of multicrystalline silicon materials. They are available in 180, 200 and 220 micron thicknesses. The front contact of the solar cells is of 2mm busbars and the back contact of the solar cells is of 4mm busbars. These multicrystalline solar cells are available in blue anti-reflection coating. They are designed in line screen printed metallization. The standard cells are available in different classes. The S156PS400 model has a maximum power of 4.00W and has an efficiency of 16.40%. Its open circuit voltage and short circuit current are 622V and 8.28A, respectively.
