title = "Modulated surface texturing of temporary Al foils substrates for high-efficiency thin-film, flexible solar cells",
abstract = "This work focuses mainly on development of modulated surface texturing of Al substrate for thin-film, silicon-based, flexible solar cells. We compared the current roll-to-roll process at industrial level with a newly developed lab-scale texturing that offers better performance both with KOH and NaOH etching of Al foil. The kinetics of these etching chemicals, modelled with an Arrhenius equation, is evaluated in both methods, activation energy and pre-exponential factor are calculated depending on etching concentration. We also deployed a new roll-to-roll experiment that shows better optical properties than the baseline. Finally, we also show the first results of micromorph tandem devices on the baseline texturing.
