SCHMID receives pv magazine award for DW texturing process

  • SCHMID’s process for the texturing of diamond-wire-cut multi-wafers convinces the jury. Experts expect the current production costs of solar modules to drop by three to six percent

SCHMID has received the pv magazine award in the category “Top Innovation” for its latest development, called DW PreTex. An independent jury of scientists and managers within the PV industry agrees: The inline process for texturing of diamond-wire-cut multi-wafers brings the PV manufacturers significant benefits, expected to be in the range of three to six percent.

Diamond-wire-cut wafers are 0.06 to 0.08 Euros cheaper than slurry-cut wafers. So far, this cost advantage could not be realized for multi-crystalline wafers, because there was no cost-effective  method for texturing the relatively smooth surface. SCHMID’s “Top Innovation” is about to change the landscape: DW PreTex only requires one process step to enable the processing of diamond-wire-cut multi-wafers with the standard HF/HNO3 texture. The pre-treatment with DW PreTex costs less than 0.01 Euro per wafer. This innovation enables PV manufacturers to save 0.05 to 0.07 Euros per wafer.

Furthermore, the DW PreTex process works with consumables that are already available in the PV industry. This means that existing production lines can be easily upgraded by adding one compact wet process system. The pre-treatment process can be integrated either at the end of the wafer production or at the beginning of the cell production. Due to the advantages of SCHMID’s solution there is strong interest from the market for the new system. First orders for industrial mass production with 500 MW have already been placed and an additional 5 GW are expected by the middle of the year.
