High-mobility inorganic CuCrO nanoparticles are co-utilized with conventional poly(bis(4-phenyl)(2,5,6-trimethylphenyl)amine) (PTAA) as a hole transport layer (HTL) for perovskite solar cells to improve device performance and long-term stability. Even though CuCrO nanoparticles can be readily synthesized by hydrothermal reaction, it is difficult to form a uniform HTL with CuCrO alone due to the severe agglomeration of nanoparticles. Herein, both CuCrO nanoparticles and PTAA are sequentially deposited on perovskite by a simple spin-coating process, forming uniform HTL with excellent coverage. Due to the presence of high-mobility CuCrO nanoparticles, CuCrO/PTAA HTL demonstrates better carrier extraction and transport. A reduction in trap density is also observed by trap-filled limited voltages and capacitance analyses. Incorporation of stable CuCrO also contributes to the improved device stability under heat and light. Encapsulated perovskite solar cells with CuCrO/PTAA HTL retain their efficiency over 90% after ~900-h storage in 85 °C/85% relative humidity and under continuous 1-sun illumination at maximum-power point.

Semiconductor metal oxide with TiO nanoparticles removes hazardous compounds from environmental samples. TiO nanoparticles have shown potential as an efficient photocatalyst by being employed as a nano-catalyst for the breakdown of organic contaminants in wastewater samples. To separate substances from contaminated samples, combined UV and visible light irradiation has been used.

As an important biomarker of lung cancer, -propanol at the sub-ppm level is still challenging to be detected for a simple and immediate early diagnosis. In this work, a new -propanol gas sensor with an ultralow detection limit down to 100 ppb is presented using AgCrO nanoparticles synthesized by a simple hydrothermal method. Compared with the congeneric CuCrO and commercial SnO, AgCrO exhibits prevailing performances, including a higher selectivity, dynamic response, and logarithmical linearity but lower working temperature.

We demonstrate CuCrO (CCO) nanoparticle (NP)-polyimide (PI) composite film as a saturable absorber (SA) to regulate the output characteristics of passively Q-switched fiber laser at 1.55 μm. Based on the reverse saturable and saturable absorptions of the CCO NP-PI film, the passively Q-switched fiber laser expressed two stages with the increase of pump power for substantial performance enhancement.

Nanostructured metal oxide semiconductors have received great attention used as the chemiresistive layer of gas sensor to detect the volatile organic compound recently. As indispensable complementary parts for dominative n-type semiconductors, the p-type metal oxides based gas sensors fail to be studied sufficiently, which hampers their practical applications. In this work, the p-type delafossite CuCrOnanoparticles were synthesized, characterized, and tested for gas sensing, followed by the first principles calculations to simulate the generation of chemiresistive signal.
