“…The applications for thin films fabricated by spray pyrolysis are very broad, they are used as barrier layers [10,26], for semiconductor devices such as solar cells [3,11,[14][15][16][17]22], sensors [3,11,14,22], or photoactive layers [22]. Electrochromic materials [13,27], catalytically active thin films [14,16,21] and battery components [14,16,21,28] are also fabricated by means of spray pyrolysis.…”
