3D nanographene precursor suppress interfacial recombination in PEDOT: PSS based perovskite solar cells

Ionization of hole-transporting materials as a method for improving the photovoltaic performance of perovskite solar cells

“…S5a†). 88–90 The electronic structure calculations show that the MAI-terminated (001) surface formation does not incorporate any defect state inside the bandgap, revealing defect-tolerance of MAPbI 3 towards these surface formations (Fig. S5b†).…”

Recent Advances of Inverted Perovskite Solar Cells

“…Although PTAA possesses an appropriate energy band structure, including a shallow HOMO and a deep lowest unoccupied molecular orbital (LUMO), the poor wettability of the perovskite precursor on PTAA was the most fatal drawback for fabricating a highly crystalline perovskite with low interface nanovoids and defects. To overcome these challenges, a range of interlayers has been utilized, such as 2D materials, , alkyl­ammonium halides, − organic small molecules, and hydrophilic polymers (Table ). In 2020, an anionic conjugated polyelectrolyte called MPS6-TMA was designed.…”

Bifacial Perovskite Solar Cells with Gold Transparent Electrodes Grown on Molybdenum Disulfide Surfaces

“…Due to their relatively high energy conversion efficiency and low costs, silicon-based solar cells have gradually become the mainstream product in the commercial market . Different approaches such as cadmium telluride (CdTe) thin-film solar cells, copper indium gallium diselenide (CIGS) solar cells, and perovskite-based solar cells have also been proposed for possible solar cell applications. − However, due to the Shockley–Queisser efficiency limit, the theoretical power conversion efficiency (PCE) limit of single-junction photovoltaic cells is limited at ∼30%. ,, In this case, it is difficult to further reduce the power generation cost of Si-based solar cells, which will hinder the replacement of fossil fuels by solar cells. One promising solution to this problem is tandem solar cells.…”
