Consensus in the solar industry is that it is gradually shifting towards monocrystalline cell technology from the more common multicrystalline (also called multicrystalline) cells and modules. The introduction of passivated emitter rear contact (PERC) cell technology has markedly increased the efficiency of monocrystalline cells, making them an economically attractive option for many projects. However, the use of multicrystalline modules still dominate the market in India, though developers have begun to seriously consider mono perc modules as they come with several important advantages.
