Abstract

Modelling and simulation techniques were used to understand the fluid flow patterns inside the silicon texturing system operating under the gas-lift effect (GLE) for solar cell applications. Experiments were performed which confirmed the validity of the simulation model and the simulated results. It was determined that due to the original non-optimal inlet, the fluid flow pattern and the non-uniform fluid velocity distribution inside the system resulted in the generation of lower velocity regions on the surface of the textured silicon. The simulation tool validated the correlation of the lower fluid velocity with the reduced surface coverage, uniformity and subsequent less optimal surface reflectivity. Various inlet designs were modelled and evaluated for optimal performance. The best-case inlet design was fabricated and tested resulting in the validation of the simulation work and significant improvement in the GLE texturing system performance. With the new inlet design, as the fluid velocity reaches and goes beyond some critical value (in this case 0.047 m s−1) in areas that had shown lower velocity in the original inlet design (mainly close to the inlet and side walls), the observed morphology and surface reflectivity improve significantly with values very similar to those of the higher velocity areas.
