Results show that the initial texturing topology and reflectivity is not affected by the subsequent rinses and the doping uniformity is also the same as with the standard chemicals. Texturing of the surface is the first step of the single emitter photovoltaic (PV) manufacturing process for both mono- and multi-crystalline silicon wafers.
In the case of NaOH + IPA solution, the processing time was about twice (i.e. 30 min) as long as that in the case of texturing using KOH + additive, which was only 15 min. In addition, the resulting size of the pyramids on the textured surfaces to achieve high efficiency varies by type of the solar cells fabricated.
Silicon surface texturing is an effective way of light trapping for solar cells application [9, 12]. Light trapping is typically achieved by altering the way the light travels by making it incident on an angled surface in the solar cell.
