Constructing Monolithic Perovskite/Organic Tandem Solar Cell with Efficiency of 22.0% via Reduced Open‐Circuit Voltage Loss and Broadened Absorption Spectra

Abstract

The average values and the deviations are calculated from 20 independent devices; b) The current density calculated from the EQE spectra.

Solid additive tuning of polymer blend morphology enables non-halogenated-solvent all-polymer solar cells with an efficiency of over 17%

“…Grazing incidence wide-angle X-ray scattering (GIWAXS) experiments were conducted to investigate the morphology features in the pristine and blend films. 43,44 The 2D GIWAXS diffraction patterns and the corresponding line-cut profiles of the neat films of PBQ6 and PYF-T- o are shown in Fig. S13 and S14 (ESI†).…”

A Perspective on Perovskite Solar Cells: Emergence, Progress, and Commercialization

“…In addition, perovskites have been demonstrated as promising candidates in multi-junction cells due their easily tunable bandgap through constituents ( Al-Ashouri et al, 2020 ; Chen et al, 2021 ; Chen et al, 2022 ; Lin et al, 2022 ; Qin et al, 2022 ). The state-of-the-art perovskite-on-silicon tandem solar cell has achieved a PCE of 29.52% in Oxford PV on approximately 30 × 30 cm 2 device area ( Al-Ashouri et al, 2020 ).…”

Recent progress in use of MXene in perovskite solar cells: for interfacial modification, work-function tuning and additive engineering

“…Furthermore, the main characteristics of a long carrier diffusion length, low exciton binding energy, and broad absorption coefficient in perovskite solar cells are also highly dependent on the quality of beneficial interfacial interactions with the photoactive perovskite as well as in the charge transfer layers. [19][20][21][22] To deal with these issues currently there are many processing approaches in which 2D materials are now employed in the perovskite absorbing layer as well as in the charge extraction layers in PSCs, to improve the compatibility at the interfaces, which has striking impacts on the morphology and photovoltaic performance of the perovskite solar cells. [22][23][24][25][26][27][28][29] Nanomaterials with a thickness of at least one atomic layer are known as two-dimensional (2D) nanomaterials.…”
