We developed lead-free perovskite solar cells, because lead is harmful to the human body. In this study, the lead-free perovskite layers were fabricated using antimony, bismuth and silver. Normal (n-i-p) and inverse (p-i-n) structures were tried f...

In perovskite solar cells (PSCs), electron selective layers (ESLs) assume a crucial role in blocking holes and transporting electrons for high performances. To achieve low-temperature solution processing of PSCs, organic n-type materials such as f...

Using the simple and cost-effective methods, spin-coated ZrO2-polymer composite/spray-deposited TiO2-compact multilayer antireflection coating film was introduced. With a single TiO2-compact film on the surface of a crystalline silicon wafer, 5.3%...
Research of CH(3)NH(3)Pbl(3) perovskite solar cells had significant attention as the candidate of new future energy. Due to the toxicity, however, lead (Pb) free photon harvesting layer should be discovered to replace the present CH3NH3PbI3 perovs...

NANO CONVERGENCE 4(1) 18 2017年 [査読有り]
We confirmed the influence of ZnO nanoparticle size and residual water on performance of all inorganic perovskite solar cells. By decreasing the size of the ZnO nanoparticles, the short-circuit current density (JSC) and open circuit photovoltage (...
