Meanwhile, the FF of all SHJ solar cells with the ITO buffer layer increased by approximately 0.2 %, corresponding to the reduction in series resistance (Rs). Compared to monolayer ITO, the Rs of bilayer ITO improve by 0.20 mΩ for S1, 0.22 mΩ for S2, 0.26 mΩ for S3, and 0.26 mΩ for S4, respectively, brought by reduced sputtering damage for ...

Feb 10, 2025 · In this study, the potential of reactive plasma deposition (RPD) is demonstrated for fabricating indium tin oxide (ITO) as an efficient buffer layer in inverted wide-bandgap perovskite solar cells (PSCs).

Sep 13, 2024 · In this study, the thicknesses of ITO layers used as the front electrode and as the recombination layer are reduced to decrease the optical losses. Thickness range is chosen by taking optical simulation on solar cells and ITO thin-film …

Mar 22, 2025 · The perovskite solar cell (ITO/Cu 2 O/CH 3 NH 3 PbI 3 /PCBM/Ag) was fabricated by Weili, et al. 21 using Cu 2 O as HTL. The Cu 2 O film was prepared using thermal oxidation of vacuum evaporated Cu ...

Indium Tin Oxide (ITO) is a key material used in solar cells. Solar cells are devices that turn sunlight into electricity, and ITO helps make them work better. It is both transparent and conductive, meaning it allows light to pass through while also carrying an electric current.

2 days ago · SHJ solar cells face a significant challenge in achieving their theoretical efficiency limits due to light reflection at the air–cell interface. This reflection reduces photon absorption, which limits photocurrent generation and hinders the widespread adoption of SHJ technology.

The indium tin oxide (ITO) thin film plays an important role in the silicon heterojunction (SHJ) solar cells, which acts as not only a carrier transport layer in vertical and lateral directions but an anti-reflection layer as well.

Nov 15, 2019 · The most common solution for the front side contact in semi-transparent perovskite solar cells or tandem solar cells is using a transparent conductive oxide (TCO), often tin-doped indium oxide (ITO) or indium-doped zinc oxide (IZO).

4 days ago · Narrow-bandgap perovskite solar cells (NBG PSCs): ITO was treated the same as WBG PSCs. The PEDOT:PSS was spin-coated on ITO substrates at 5000 rpm for 30 s, and annealed at 150 °C for 20 min in ...

The simulation model was initially validated through calibration against an experimental AgBiI 4-based solar cell, featuring the structure ITO/SnO 2 /AgBiI 4 /PTAA/Au. Loss analysis of the calibrated cell revealed that the cell suffers from different issues, including high defects and low absorption capabilities.
