Two-dimensional MXenes for stabilization of large area perovskite solar cells and modules
In this proposal I would use the VIPERLAB infrastructure CHOSE-S2S for study the stabilization effect of two-dimensional MXenes based on Ti, V, Nb and Mo for large area perovskite solar cells and modules. I propose to consider the impact of MXenes as dopant for the perovskite absorber as well as interlayer. Stabilization will be assessed by using light soaking.
Status: Ongoing
Date of proposal: 02/12/2021
Start date: 13/06/2022
End Date: 20/06/2022
Used Instruments: CHOSE-S2S line
Experimental Technique: Synthesis and characterization of Mxenes. Fabrication and testing of perovskite solar cell devices.
Experiment Description: Investigation of the stabilization effect of two-dimensional MXenes (based on Ti, V, Nb, and Mo) on large area perovskite solar cells and modules. Study of MXenes as a dopant for the perovskite absorber and as an interlayer.
Type Samples: MXenes (Ti3C2Tz, Ti3C2Cl2, Nb2CTz).
Sample Description: Ti3C2Tz and Nb2CTz MXenes produced via wet chemical etching. Ti3C2Cl2 MXenes produced via molten salt synthesis.
Experiment Data Type: Work Function (WF) measurements of Mxenes. Stability and performance data of perovskite solar cell devices with different Mxenes.
Characterization Technics: XRD and SEM for initial characterization of Mxenes. Electrical and photovoltaic characterization of solar cells.
Characterization Data Type: WF of MXenes with different terminations. Performance data of perovskite solar cells with and without Mxenes.
Analyzed Data: Comparative analysis of the stability of perovskite solar cells with different MXene compositions. WF measurements for different MXenes and their impact on solar cell performance.
Main Targets Project: To enhance the stability of large area perovskite solar cells and modules using two-dimensional MXenes. To understand the role of MXenes in modifying the electronic properties of perovskite solar cells.
Main Achievements Findings: Successfully measured WF of freshly produced Ti3C2Cl2 MXenes and compared it with Ti3C2Tz MXenes. Fabricated perovskite solar cell devices with different MXene compositions and observed that Cl-based MXenes show higher stability compared to those with mixed terminations. Highlighted the potential of MXenes in improving the stability and performance of perovskite solar cells.
Review 2
How would you describe your experience with the VIPERLAB opportunity? How did the experience/visit at CHOSE meet your expectations?
I had a very positive experience during my short-term research stay at CHOSE. During my stay, I had 30 min talk in which I presented my main research activities; I have fully completed my research program, and I have a new collaboration that is ongoing.
Did you face any difficulties during your visit or application process?
The application process is quite simple and does not take much time. I did not have any problems during my visit as we planned the visit and experimental activities well in advance.
Does this VIPERLAB experience at CHOSE bring you closer to your research objectives? How?
In-person communication and the opportunity to participate in an experiment is always better than sending samples and exchanging emails.
What other VIPERLAB activities have you participated in, or would you like to participate in?
I did not participate in other VIPERLAB project. I would like to participate again.
Do you intend or already did publish/present your collected results in a paper or conference?
We are finalizing the first draft of the manuscript based on the results obtained during my stay at CHOSE.
