Influence of the ratio of surfactant additives on the anisotropic etching process used to make small pyramids for use in solar cells

In addition, the cell with the highest efficiency had an increase of 4.57% in power, an increase of 3.1% in the short-circuit current, and an increase of 1.43% in the open-circuit voltage. In summary, microstructural, reflectance, IQE, and I–V measurements revealed that the best cell was formed using an optimal SA volume of 0.4 L.
