“…The estimated PCE value from the J – V curve was 13% in the sample device with an open-circuit voltage V OC of 1.03 V, a short-circuit current density ( J SC ) of 21 mA cm −2 , and a fill factor ( FF ) of 61%; the PCE in this case is much higher than the PCE value of 8% in the reference device with V oc = 0.95 V, J sc = 19 mA cm −2 , and FF = 45%. These PV results are consistent with previous results for perovskite PV cells 26 , 43 , 44 . Thus, it is obvious that the perovskite photodiodes based on the NiO x HTL exhibit improved PV performance.…”

Hybrid organic–inorganic perovskite materials provide noteworthy compact systems that could offer ground-breaking architectures for dynamic operations and advanced engineering in high-performance energy-harvesting optoelectronic devices. Here, we demonstrate a highly effective self-powered perovskite-based photodiode with an electron-blocking hole-transport layer (NiOx). A high value of responsivity (R = 360 mA W−1) with good detectivity (D = 2.1 × 1011 Jones) and external quantum efficiency (EQE = 76.5%) is achieved due to the excellent interface quality and suppression of the dark current at zero bias voltage owing to the NiOx layer, providing outcomes one order of magnitude higher than values currently in the literature. Meanwhile, the value of R is progressively increased to 428 mA W−1 with D = 3.6 × 1011 Jones and EQE = 77% at a bias voltage of − 1.0 V. With a diode model, we also attained a high value of the built-in potential with the NiOx layer, which is a direct signature of the improvement of the charge-selecting characteristics of the NiOx layer. We also observed fast rise and decay times of approximately 0.9 and 1.8 ms, respectively, at zero bias voltage. Hence, these astonishing results based on the perovskite active layer together with the charge-selective NiOx layer provide a platform on which to realise high-performance self-powered photodiode as well as energy-harvesting devices in the field of optoelectronics.

“…The reason is that CsPbI 3 QDs, a wide-energy gap material, show a small strain at the interface of CsPbI 3 QDs and MAPbI 3 [ 18 , 19 ], promoting film growth. Some related studies present the performance of photovoltaic devices, such as solar cells, which are improved after doping quantum dots into perovskite films [ 20 , 21 ]. The surface of composite perovskite films is further optimized via oxygen plasma treatment at different powers, from 20 to 80 W, as shown in Figure 1 b.…”

In this study, we describe composited perovskite films based on the doping of lead cesium triiodide (CsPbI3) quantum dots (QDs) into methylammonium lead iodide (MAPbI3). CsPbI3 QDs and MAPbI3 were prepared by ligand-assisted re-precipitation and solution mixing, respectively. These films were optimized by oxygen plasma treatment, and the effect of powers from 0 to 80 W on the structural properties of the composited perovskite films is discussed. The experimental results showed that the light-harvesting ability of the films was enhanced at 20 W. The formation of the metastable state (lead(II) oxide and lead tetroxide) was demonstrated by peak differentiation-imitating. A low power enhanced the quality of the films due to the removal of organic impurities, whereas a high power caused surface damage in the films owing to the severe degradation of MAPbI3.

“…As one of the most competitive materials in the photovoltaic field, organic-inorganic hybrid halide lead perovskites (ABX 3 , where A is a monovalent cation, B is a divalent cation and X is a halide ion) have attracted great attention in recent years [1][2][3][4]. Through structural engineering [5,6], surface interface engineering [7,8], solvent engineering [9,10] and incident light management engineering [11,12], current organic-inorganic hybrid perovskite-based photovoltaic devices have demonstrated power conversion efficiencies (PCEs) of over 25.2% [13].…”

We demonstrate a method to enhance the power conversion efficiency (PCE) of MAPbI3 perovskite solar cells through localized surface plasmon (LSP) coupling with gold nanoparticles:CsPbBr3 hybrid perovskite quantum dots (AuNPs:QD-CsPbBr3). The plasmonic AuNPs:QD-CsPbBr3 possess the features of high light-harvesting capacity and fast charge transfer through the LSP resonance effect, thus improving the short-circuit current density and the fill factor. Compared to the original device without Au NPs, a 27.8% enhancement in PCE of plasmonic AuNPs:QD-CsPbBr3/MAPbI3 perovskite solar cells was achieved upon 120 μL Au NP solution doping. This improvement can be attributed to the formation of surface plasmon resonance and light scattering effects in Au NPs embedded in QD-CsPbBr3, resulting in improved light absorption due to plasmonic nanoparticles.
