我们将透明抗反射涂层和透明电极集成到柔性无色聚酰亚胺(CPI)基板上,以制造高性能柔性钙钛矿太阳能电池。通过在CPI基板的两侧溅射最佳的等离子体聚合氟碳化合物(PPFC)抗反射涂层和InGaTiO(IGTO)电极膜来制造多功能PPFC/CPI/IGTO基板。通过使用低折射率(1.38)的PPFC作为抗反射涂层,PPFC/CPI/IGTO底物的透明度增加了1.2%。此外,由于PPFC和IGTO层的非晶特性,PPFC/CPI/IGTO基板在弯曲测试期间即使在10,000个循环之后也显示出恒定的薄层电阻和透射率变化。柔性钙钛矿太阳能电池,在PPFC/CPI/IGTO基板上制造,在PPFC抗反射涂层沉积后,电流密度增加1.48mA/cm2。这些结果证实,PPFC/CPI/IGTO基材对高温处理具有耐久性,灵活,并表现出优异的电气特性。这增强了柔性钙钛矿太阳能电池的效率和耐久性。此外,疏水性PPFC层允许非柔性钙钛矿太阳能电池的自清洁。鉴于这些属性,PPFC/CPI/IGTO结构已被公认为是柔性钙钛矿太阳能电池多功能基板的良好选择,展示提高绩效的潜力。
我们已经确认了PPFC/CPI/IGTO基板对高温处理的耐久性,他们的灵活性,透明度,以及它们特殊的电性能,建议将它们作为FPSCs的主要选择。
We integrated transparent antireflective coatings and transparent electrodes onto flexible colorless polyimide (CPI) substrates to fabricate high-performance flexible perovskite solar cells. Multifunctional PPFC/CPI/IGTO substrates were fabricated by sputtering the optimal plasma-polymerized fluorocarbon (PPFC) antireflective coating and InGaTiO (IGTO) electrode films on both sides of the CPI
substrate. By applying PPFC with a low refractive index (1.38) as an antireflective coating, the transparency of the PPFC/CPI/IGTO
substrate increased by an additional 1.2%. In addition, owing to the amorphous characteristics of the PPFC and IGTO layers, the PPFC/CPI/IGTO
substrate showed constant sheet resistance and transmittance change even after 10,000 cycles during the bending tests. The flexible perovskite solar cells, fabricated on the PPFC/CPI/IGTO
substrate, exhibited an increase in current density of 1.48 mA/cm2 after the deposition of the PPFC antireflective coating. These results confirmed that the PPFC/CPI/IGTO
substrate was durable against high-temperature treatment, flexible, and exhibited excellent electrical characteristics. This enhanced the efficiency and durability of the flexible perovskite solar cells. Moreover, the hydrophobic PPFC layer allowed the self-cleaning of inflexible perovskite solar cells. Given these attributes, the PPFC/CPI/IGTO structure has been recognized as a good choice for multifunctional substrates of flexible perovskite solar cells, presenting the potential for enhancing performance.
We have confirmed the durability of PPFC/CPI/IGTO substrates against high-temperature treatment, their flexibility, transparency, and their exceptional electrical properties, suggesting them as a prime selection for FPSCs.
