The role of structural parameters on efficiency and transparency of semi-transparent non-fullerene organic solar cell

Abstract

Semitransparent organic solar cells have become attractive recently because of their photon harvesting in the near-infrared and ultraviolet range and passing in the visible light region. Semitransparent organic solar cells with ITO/ZnO/PBDB-T:ITIC/MoO3/Ag/MoO3 structure have been studied in this work and the effects of PBDB-T:ITIC active layer thicknesses and the transparent top electrode, MoO3/Ag/MoO3, thickness on the solar cell performance such as I-V characteristics, the power conversion efficiency, the average visible transmittance, and the color coordinates in the CIE color space are investigated. The drift–diffusion model, including the density of exactions, and their displacement is used to model the devices. The model is examined with experimentally reported devices, where there is a very good agreement between them, then is applied to the new structures. The obtained results show that the average visible transmittance of more than 45% is achievable for these structures with reasonable power conversion efficiency.

Improving Efficiency of Semitransparent Organic Solar Cells by Constructing Semitransparent Microcavity

“…Using microcavity changes the color coordinates slightly, but the device can transmit high-quality light with a near-white sensation to the human eye with a very small changing the original color of an object. It should be pointed out that the PCE and AVT data in this paper are calculated using the model reported in our previous article [32]. As usual, the practical device PCE and AVT may be smaller than the calculated PCE and AVT data proposed in this paper.…”

“…To calculate the device's performance parameters such as short-circuit current, Jsc, open-circuit voltage, Voc, fill-factor, FF, and power conversion efficiency, PCE, we used the drift-diffusion model, where, in addition to considering the density of excitons, their displacement is taken into account. The AVT value is calculated and the model is extensively explained in our previous publications [32].…”

Unraveling the Impact of Thickness on Active Layer Morphology and Device Performance of Semitransparent Organic Solar Cells: A Comprehensive Study

“…Controlling the rpm makes it possible to tune the morphology of the active layer to improve the device's performance. 26,27 One of the strikingly notable characteristics of the OSCs is their semitransparency, which opens possibilities for usage in power-generating windows, curtains, and other architectural elements for buildings, cars, and other vehicles. 28−30 Another attractive feature is the tunability of the optical absorption spectra of the organic semiconductors in the OSCs.…”

“…Therefore, the rpm used during the coating process is a vital parameter to consider when optimizing the morphology of the active layer in the OSCs. Controlling the rpm makes it possible to tune the morphology of the active layer to improve the device’s performance. , …”
