Development of lead halide perovskite, or methylammonium lead iodide (MAPbI₃) perovskite, has advanced rapidly in terms of photovoltaic output in shorter time compared to more mature and developed solar cells, such as dye sensitized solar cell or Si based solar cells. From 2009 when PSCs was first adopted by Miyasaka et al. until development in 2012, its efficiency (η) has extended to higher than 10 %. Further development in 2013 and 2014 has further increased η of more than 15 % and 20 %, respectively. ZnO based PSCs is developed based on high electron mobility of ZnO material. In this report, ZnO based PSCs is reported and have improved coverage of perovskite over ZnO nanorods array (NRA) surface. Such improvement also leads to improvement of η although the value of η is still very low (less than 1 %).
