Innovative PERC technology
PERC technology, also known as Passivated Emitter Rear Cell or rear-side passivation, is a key technology in Offgridtec olp solar modules that increases the efficiency of solar cells. It creates a dielectric layer between the conventional aluminium metallization and the silicon wafer layer on the back of the cell. A laser is applied to this layer to create tiny holes. This dielectric layer reflects light, which normally penetrates through to the rear side without generating charge carriers, back into the solar cell. This gives photons an extra chance to generate electricity. PERC technology improves efficiency across different wavelengths, increases the likelihood of electrons contributing to electricity generation and helps to reduce system costs and increase energy yield per unit area.
