The high interface quality between <inline-formula xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink> <tex-math notation=LaTeX>$beta $ </tex-math></inline-formula> -Ga2O3NW electron transport layer (ETL) and CH3NH3PbI3 made the device to operate in self-powered mode. Also, the performance of D2 improved significantly due to the existence of wide band gap and high mobility NiO NW array as a hole transport layer (HTL). At zero bias voltage, very low dark current of 0.32 nA and 4.54 nA were observed for D1 and D2, respectively. Moreover, D2 produced a high responsivity of 254 mA/W which was ~9 times higher than that of D1 (28 mA/W) under self-power mode. Furthermore, there was a significant improvement in specific detectivity of D2 ( <inline-formula xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink> <tex-math notation=LaTeX>$5.23times 10^{11}$ </tex-math></inline-formula> Jones) as compared to D1 ( <inline-formula xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink> <tex-math notation=LaTeX>$2.99times 10^{11}$ </tex-math></inline-formula> Jones)." @default.
