Abstract
In this work, a novel diluted carbonate/bicarbonate solution was applied for texturization of monocrystalline silicon for solar cells. The content of reactants in the solution was decreased 20 times with respect to the previously optimum found by our group and 12 times with respect to the lowest values reported in the literature as optimum. The use of this low-cost and nonhazardous solution, free of additives as isopropyl alcohol, can reduce costs in solar cell processing.
