From 2014 to 2018 the number of “thin films” scientific publications have raised by almost 75%. More than 140.200 publications related to thin films from the main scientific journals (Nature, Elsevier, Springer, Taylor & Francis, and Wiley) have been examined to deem its main study topics. *
“New material characterization and manufacturing” is the principal research topic representing 44% of the scientific literature analyzed related to thin films. This topic includes changes in thin film properties relative to electronics, optics, magnetism, and mechanics.
The next research topic with high presence is “solar cells characterization“, representing 17% of all literature analyzed. For those characterizations, they analyse layers or multilayers of different films deposited by PVD sputtering techniques, like perovskite/CIGS (multilayer film made of copper, indium, gallium, and selenide), layers doped with plasmons or kesterite/CZTSSe (multilayer film made of copper, zinc, tin and selenide/sulfur-selenium,).
The main differences appear in solar cells characterization. The principal layers used in this case are kesterite layers and in a smaller proportion, perovskite layers. Those layers are in primary research phases but, it seems that in Spain and Portugal it’s taking more and more strength.
