Modification of electron-transport layers with mixed RGO/C60 additive to boost the performance and stability of perovskite solar cells: A comparative study

Enhancing the stability and efficiency of carbon-based perovskite solar cell performance with ZrO2-decorated rGO nanosheets in a mesoporous TiO2 electron-transport layer

“…Suppressing charge recombination in a solar cell increase its V OC parameter. 37,38 Notably, the suppression of charge recombination in the rGO/ZrO 2 -doped ETL was higher than in the rGO-doped ETL, which concords with the results listed in Table 1. The reason behind the PL quenching in rGO/ZrO 2 is the faster-transferring path for the photogenerated carriers from the FAPbI 3 to the FTO, which decreases the recombination rates in the device.…”

“…When 6.8% CHX additive is added to the FAI:MACl precursor solution, the control device’s maximum PCE, which is 19.02% without this material, is dramatically raised to 22.01%, primarily improving J SC , V OC , and FF. The reason for this is mainly that the 6.8% addition created more effective perovskite films than the control device, which had lower GBs, higher photo electron–holes generation, and lower trap-assisted charge recombination. − On the other hand, the findings of FESEM and XRD studies show that increasing the CHX content from 6.8% to 10.2% reduces the solar cell performance, including J SC , V OC , and FF, due to the disruptive crystallinity of perovskite films. Figure f displays the IPCE spectra for PSC devices with and without the optimal concentration of CHX additive, which is near the J SC values derived from the aforementioned J–V curves.…”

Additive engineering with sodium azide material for efficient carbon-based perovskite solar cells

“…Indeed, the FF and J SC improvements can be attributed to the boosted perovskite film quality, reduced non-radiative recombination, and facilitated charge extraction. 37,38…”

“…It was concluded that the Indeed, the FF and J SC improvements can be attributed to the boosted perovskite film quality, reduced non-radiative recombination, and facilitated charge extraction. 37,38 Long-term stability is one of the most important performance criteria for C-PSCs' future commercial uses. Therefore, the longevity of the pristine and modified C-PSCs was assessed by tracing the PCE progression in a dry box with a relative humidity of lower than 20% at room temperature in the dark (Fig.…”
