Highly Efficient Multi-crystalline Solar Cells Using Rear Surface Passivation Technology☆
2014
Abstract In this work, we have successfully demonstrated the rear side passivation technology applied to multi-crystalline p-type wafers. The AlOx/SiNx stack was selected as rear side passivation layer combined with suitable laser opening source and metallization materials. The performance of multi-crystalline cell reached an efficiency level of 18%-19% applying this technology and the light induced degradation and module power output performance are attractive compared with current cell type.
