6 FAQs about [Photovoltaic support capping]
Does full-end-capping engineering improve photovoltaic performance and stability?
Therefore, it is believed that full-end-capping engineering provides a very simple, versatile and general approach to improve photovoltaic performance and stability of the OSCs. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
Can end-capped polymer donors improve photovoltaic performance and stability?
Besides, the devices with end-capped polymer donors also possess better stability than that with PM6 by removing unreacted bromine and trimethylstannyl end groups. Therefore, it is believed that full-end-capping engineering provides a very simple, versatile and general approach to improve photovoltaic performance and stability of the OSCs.
What is the experimental method for investigating capping layer design guidelines?
The experimental method for investigating capping layer design guidelines. A. Machine Learning and Feature Importance Rank The 21 capping layer materials, including tetrapropyl-ammonium iodide (TPAI) and phenyltriethylammonium iodide (PTEAI), with various concentrations (5-15 mM) are deposited and annealed at temperatures between 50°C-125°C.
Does end-capping affect device stability?
To study the effect of end-capping on the device stability, all unencapsulated devices were tested for storage stability, thermal stability and light stability in a N 2 glove box ( Fig. 6 a–d and Fig. S20 ). After storage for 1200 h, the stability of the end-capped devices is better than the PM6:Y6 device.
Is pteai a stable capping-layer material?
The statistical analysis (ANCOVA) of the films shows that the red degradation onset of the most stable capping-layer material in this study, PTEAI, is statistically significantly different, with 95% confidence level, in comparison to other materials and bare MAPbI 3 film (Supplementary Fig. 8).
How do you make a capping layer solution?
Capping-layer solutions were made in three different concentrations, 5, 10, and 15 mM, by mixing ammonium iodide/ammonium bromide powder with isopropyl alcohol, pure, ACS reagent, ≥99.5% (Sigma-Aldrich). A list of ammonium iodide/ammonium bromide powder manufacturers is listed in Supplementary Table 5.
