“…Here, their FF and V OC values should be further improved to obtain high performance PSCs. Besides the optimization of Ni/Au mesh electrode, more efficient charge transport layers [3,39], and interface passivation [1,40] are feasible approaches to achieve this goal. Furthermore, from Figure 7, the PSCs based on Ni/Au mesh and ITO present a similar trend of PCE degradation.…”

Indium thin oxide (ITO)-free planar perovskite solar cells (PSCs) were fabricated at a low temperature (150 °C) in this work based on the transparent electrode of photolithography processed nickel/gold (Ni/Au) mesh and the high conductivity polymer, PH1000. Ultrathin Au was introduced to increase the conductivity of metal mesh, and the optimal hexagonal Ni (30 nm)/Au (10 nm) mesh (line width of 5 μm) shows a transmittance close to 80% in the visible light region and a sheet resistance lower than 16.9 Ω/sq. The conductive polymer PH1000 not only smooths the raised surface of the metal mesh but also enhances the charge collection ability of metal mesh. The fabricated PSCs have the typical planar structure (glass/Ni-Au mesh/PH1000/PEDOT:PSS/MAyFA1−yPbIxCl3−x/PCBM/BCP/Ag) and the champion PSC (0.09 cm2) obtains a power conversion efficiency (PCE) of 13.88%, negligible current hysteresis, steady current density and PCE outputs, and good process repeatability. Its photovoltaic performance and stability are comparable to the reference PSC based on the ITO electrodes (PCE = 15.70%), which demonstrates that the Ni/Au mesh transparent electrodes are a promising ITO alternative to fabricate efficient PSCs. The relatively lower performance of Ni/Au based PSC results from the relatively slower charge extraction and stronger charge recombination than the ITO based PSC. Further, we tried to fabricate the large area (1 cm2) device and achieve a PCE over 6% with negligible hysteresis and steady current density and PCE outputs. The improvements of perovskite film quality and interface modification should be an effective approach to further enhance the device performance of Ni/Au based PSCs, and the Ni/Au mesh electrode may find wider applications in PSCs and flexible devices.

“…In this work, the semitransparent CsPbIBr 2 solar cells with ultrathin Ag film electrode has been firstly used to construct a 4T perovskite/Si heterojunction (SHJ) tandem cells, their optical and electrical performance had been systemically investigated by the Silvaco Atlas device simulator. The ultrathin Ag film electrodes with an optical capping layer were successfully utilized in our previous semitransparent or bifacial perovskite solar cells [24,25,26,27,28]. For the 4T tandem applications, the optical transmission of Ag electrode at long wavelength is strongly related to the light absorption of bottom Si cell and also the overall PCE of tandem devices.…”

Wide-bandgap all-inorganic CsPbIBr2 solar cells with MoOx/Ag/TeO2 composite transparent electrode have been firstly used to construct a 4T perovskite/Si-heterojunction tandem cells. The calculation results showed that the long wavelength transmission (600 to 1100 nm) of MoOx/Ag film can be enhanced remarkably by adding a TeO2 optical capping layer. This resulted in an obviously increase of the PCE (JSC) from 10.70% (17.56 mA/cm 2) to 14.76% (24.67 mA/cm 2) for corresponding bottom Si cell in CsPbIBr2/Si devices, although the PCE of top CsPbIBr2 cell decreased from 17.52% to 16.58%, the overall PCE of tandem device has increased from 28.22% to 31.34%. This JSC-dependent PCE improvement mainly came from the more balanced light absorption, which can be understood by the optical interference induced light field redistributions in CsPbIBr2/Si devices. Specially, comparing with the original Si cell, the JSC and PCE losses in bottom Si cell have been suppressed to about 33% and 32%, which are superior to most the reported pervoskite/Si tandem cells. Therefore, the tandem of Si cell and CsPbIBr2 cell with optimized MoOx(20 nm)/Ag(8 nm)/TeO2(50 nm) transparent electrode could be the promising cost-effective photovoltaic in the future. This work is instructive to the fabrication of pervoskite/Si tandem solar cells.

“…The DMD structures in ST‐PSCs have been similar to those in ST‐OPVs. [ 33,45,48,49,73,74,78,79,117–122 ] For example, Hanmandlu et al introduced a 2,9‐dimethyl‐4,7‐diphenyl‐1,10‐phenanthroline (BCP)/Ag/MoO 3 transparent electrode for bifacial PSCs (Figure 2d). [ 79 ] In addition to providing a high dielectric constant, the BCP also functioned as a diffusion buffer layer between the electron transport layer (ETL) and the Ag electrode.…”

Organic‐ and perovskite‐based optoelectronics, which merge excellent optoelectronic properties with potentially large and high‐throughput manufacturing, have attracted attention as emerging revolutionary technologies with considerable practical applications. Herein, the recent progresses in organic‐ and perovskite‐based photovoltaics and photodetectors with integration of judicious optical structure designs are summarized. The characterization and performance metrics of such devices from the perspectives of device architecture, physics, and material science are studied. Research related to devices having dielectric mirrors, diffracted Bragg reflectors/photonic crystals, microcavities, and 2D photonic structures as design elements is discussed. Some suggestions of promising directions for future studies are concluded.
