Solar Cell
A solar cell converts solar radiation into electrical energy using a photoelectric phenomenon. When sunlight hits the silicon cell, an electric current is generated. The solar cell does not wear out in the production process, but produces a constant direct current, which the inverter converts into alternating current. The material of the cell is usually either polycrystalline or monocrystalline silicon. The cell is wear-free, long-lasting and efficient. The power generation capacity of the entire system depends on the efficiency of the solar cell.
Valoe is using either MWT (Metal Wrapped Through) or new IBC (Interdigidated Back Contact) single crystal cells in its back contact modules. In both of these, the cell contacts are on the back side of the cell, allowing the cells to be automatically and reliably connected to an electrically conductive backsheet. The choice of cells is aimed at the highest possible electricity generation capacity and a long service life. The amount of electricity produced over its lifetime and the level of production cost (LCOE) determine the profitability of the investment.

IBC - Demanding Technology
Valoe´s back contact module works best with the IBC cell. IBC cells are new technology products and have not been commercially available. Valoe has invested a lot in the cell development and in building its own cell factory in Vilnius, Lithuania. The company has modernized the traditional cell line to to fit or IBC cell production. The final installations are underway and the production will start in the summer of 2020.
