Since being discovered by Park in 2012 [1], perovskite solar cells (PSCs) have triggered rapid development and a power conversion efficiency (PCE) of 25.5%. Typically, inverted PSCs used PEDOT: PSS as the hole transport layer (HTL). However, this high cost and degradation of organic matter is a major concern for PSCs performance. Therefore, inorganic HTL materials such as NiOx attract more attention due to superior hole mobility and outstanding stability. Additionally, NiOx showed a favorable energy level with perovskite film and most importantly low-cost, and environment-friendly chemical synthesis capabilities. In this study, NiOx particles from the green synthesis process have successfully tuned from micrometer-sized to nanoparticle size of ranged 10 nm, followed by preparing a smooth and compact NiOx film and applied it as the HTL in inverted PSCs.
