The texturing process is the etching step with the highest added value. It modifies the surface of the wafer in order to create a structure that increases the amount of light absorbed in the cell, and therefore increase the overall efficiency of the cell. Current wet processes have limited efficiency and require the deposition of additional anti-reflective layers on top of the cell.


Nines ONYX texturing process delivers surface textures with superior optical properties and reflectivity as low as 2%.The cells look darker providing best in class aesthetic for all type of wafers, including multi-crystalline.

The amount of silicon removed to achieve theses textures is minimal, leading to cost saving not only on etching consumables but also on silicon, i.e. the wafers could enter the factory thinner yet the finished cell would have the same thickness as for a wet process.

ADE + PERC = 20.3% efficiency

Nines PV have demonstrated their ADE texturing process in a PERC mc-Si process, resulting in more than 20% cell efficiency in a standard industrial PERC process run in conjunction with Tier 1 cell manufacturer Hanwha Qcell. 

NINES PV and Hanwha Qcell are working together to integrate the ADE dry texturing process into the well established Q.ANTUM PERC process, using diamond wire (DW) cut mc-Si wafers. The ADE process resulted in an uplift compared to the standard reference due to the superior texturing. The cell process used for this demonstration was the same as for the reference wafers that had been textured with the incumbent acidic texturing process; no adjustment of the downstream steps were performed, yet the efficiency obtained reached 20.3%, +0.2% absolute improvement above the best reference.

The results were presented at the 2017 EUPVSEC conference in Amsterdam: " Industrial Plasma-Less Dry Texturing Method for Diamond Wire Cut mc-Si Wafers -the universal ADE texturing process ". Download the poster here

Texturing diamond wire cut wafers:

The ADE texturing process has been demonstrated with several types of crystalline wafers, inlcuding:

+ Cast wafers        + Epitaxial layers        + Diamond wire cut wafers.

More specifically, for mc-Si diamond wire cut wafers, the ADE technology provides a high performance texturing solution for industrial customers willing to move from slurry cut to diamond wire cut wafers in order to avail of the full cost benefit that this technology brings. Several industrials have already evaluated succesfully the ADE texturing. The diamond wire wafering technology is expected to grow significantly over the coming years, as detailed by the ITRPV roadmap ( The flexibility of the process allows a large variety of texture and reflectivity, down to “black-silicon” level, as would be achieved by a RIE vacuum based process.

ONYX© Process for AlBSF mc-Si

In collaboration with Fraunhofer ISE, Freiburg, Nines have demonstrated the ONYX texture process by incorporating the ADE technology in the Fraunhofer ISE pilot production line. The process developed lead to excellent results, with cell efficiencies superior to the standard wet acidic texturing process.
