The perovskite solar cells with lead halide light absorber, nano porous nickel oxide as hole-transporting materials (HTL), with methylamine iodide as lead and methyl bromide for titanium calcium deposits, there is a layer of organic/inorganic zinc oxide compound electron transport layer (ETL) to prevent calcium titanium seam exposed to air, to avoid the battery degradation.

According to the article published in the journal current materials, the conversion efficiency of the battery in the initial test was 19.1%, and the conversion efficiency was reduced by only a fifth after five months.

Dr Article co-author Sawanta Mali explained: "we use a simple way to successfully optimized the HTL and ETL protective layer of metal oxides, thereby enhancing the air stability of the perovskite solar cells.Our main goal was to low cost, high stability of n type and p type air inorganic metal oxide to replace expensive, low stability and extra additives hole-transporting materials, and thus simplify the manufacturing process of sometimes."
