Electrodeposited NiO anode interlayers: Enhancement of the charge carrier selectivity in organic solar cells

Abstract: Nickel oxide (NiO) thin films prepared by cathodic electodeposition exhibit superior electrical performace than PEDOT:PSS when used as anode interlayers of bulk-

“…In addition, different from PEDOT:PSS, the E opt of the NiO x is 3.64 eV, indicating that the conduction band is 1.85 eV above the LUMO of the donor PCDTBT (3.60 eV) and acceptor PC 71 BM (4.00 eV). This energetic orientation provides 1.75–2.15 eV energy barriers to electron collection at the anode and thus demonstrating effective electron‐blocking properties of the NiO x , which contributes to an increment in V OC through reducing leakage current and photocurrent recombination at the anode. The series resistance for the devices with NiO x HTLs and the PEDOT:PSS reference devices was calculated to be 2.65 and 4.46 Ω cm 2 , respectively.…”

“…The global energy demand for more and sustainable energy sources has increasingly led researchers to shi their attention towards clean and renewable energy sources. [1][2][3] Solar energy is one of the most abundant energy sources that can be converted into electrical energy by means of solar cells. In an effort to maximize the harvesting of solar energy, a number of solar cell technologies have been developed since the 1950s with the view to alleviate the challenges that our society is facing today, in terms of the need for more energy and environmental pollution.…”

“…Nanomaterials are gaining increasing interest in the development of several research fields. Among various nanomaterials, nickel oxide (NiO) and copper oxide (CuO) are attractive electro-catalysts in electrochemical supercapacitors [5], gas sensors [6], lithium-ion batteries [7] and different catalytic application [8,9]. Due to relatively low cost and high catalytic activity, NiO and CuO can be ideal modifying agent.…”
