Product Description:This additive is suitable to the acid polysilicon texturing system which takes HF and HNO3 as a center in the process of solar cell manufacturing. The advantages are: structure is optimized so that the cells reflectivity can be 2~3%; less than the ordinary texturing cells; less color aberration; more stable craft; electrical performance be improved; cells’ efficiency be promoted.

Runergy PT-21 polycrystalline texturing additive could optimize the suede structure :
PT-21 additive makes the polycrystalline suede smaller, deeper and more uniform, thus the reflectivity of silicon was reduced; in the suede, there is a smaller and subtler suede structure which could further enhance silicon light-trapping effect.
Polycrystalline additive’s advantages in reflectivity:Features:
1. Look more uniform, without roller printing;2. Reduce the reflectivity;3. Improve the short-circuit current;4. Mass-production efficiency enhance stability 0.08% to 0.15% ;5. No additional equipment.
