Researchers make breakthrough in light trapping technology for industrial multicrystalline silicon solar cells

Scientists from the Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) have developed a low-cost and effective technique to texture diamond-wire sawn (DWS) multicrystalline silicon (mc-Si) wafers. DWS wafers sliced using diamond-coated wires allow substantial cost savings compared to traditional slurry-cut wafers. Texturing is the process of roughening the silicon wafer surface so as to minimise front surface reflection and enhance light trapping, to boost the solar cell efficiency.
