Development of a triple-cation Ruddlesden–Popper perovskite structure with various morphologies for solar cell applications

Strong Photocurrent from Solution‐Processed Ruddlesden–Popper 2D Perovskite–MoS2 Hybrid Heterojunctions

“…[17] Various reports also show that the perovskite photodetectors are fabricated using crystalline perovskite of different morphologies such as thin films, nanocrystals, nanowires, nanoflakes, etc., which showed varied performances due to different surface area offered by the perovskites for interaction with light as well as due to the variation in the density of states. [18][19][20][21][22][23][24][25] However, the overall performance of these photodetectors also depends upon the electron transport layers (ETLs) and hole transport layers (HTLs). Attempts are made to improve the efficiencies of bulk and quasi-2D perovskite-based photodetectors using various ETLs/HTLs such Spiro-OMeTAD, [26] PEDOT:PSS, [27] P3HT, [28] and PTAA [29] as HTLs as well as PCBM [27] as ETLs.…”

Humidifying, heating and trap-density effects on triple-cation perovskite solar cells

“…Specified peaks at the XRD pattern in Fig. 3 show that the cell layers have been crystallized as well 34 . The diffraction peaks at 14.5°, 19.2°, and 28.8° are assigning to the (1 1 0), (2 0 0), and (2 2 0) crystal planes of tetragonal perovskite 34 .…”

An Innovative Anode Interface Combination for Perovskite Solar Cells with Improved Efficiency, Stability, and Reproducibility

“…As we can find from the experimental result, only 1 semicircle could be observed in the plotted curve. A simple equivalent circuit model [ 48 ] was applied to analyze the series resistance ( R s ) and recombination resistance ( R sec ) and an excellent fit of the experimental curve was found. The perovskite solar cells with and without passivation deliver a comparable R s of ≈50 Ohm.…”
