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 (Interdigitated Back Contact) single crystal cells in its back contact modules. In both of these, the cell contacts are on the backside of the cell, allowing the cells to be automatically and reliably connected to an electrically conductive back sheet. The choice of cells is aimed at the highest possible electricity generation capacity and long service life. The amount of electricity produced over its lifetime and the level of production cost (LCOE) determine the profitability of the investment.
