摘要

这项综合研究探索了利用环保型天然染料(如露兜树叶(664.1 纳米)和木瓜叶(664.0 纳米)中的叶绿素色素,以及蓝芒(536.2 纳米)中的贝特氰色素)增强染料敏化太阳能电池(DSSC)的潜力。电化学分析阐明了能带间隙,发现木瓜叶的能带间隙最小(1.387 eV),紧随其后的是山竹叶(1.389 eV)和丹参叶(1.396 eV)。这项研究通过电纺丝和相反转技术引入了一种由聚偏氟乙烯(PVDF)衍生的聚合物电解质,从而有效解决了 DSSC 开发过程中长期存在的电解质泄漏问题。SEM 表征结果和热重分析证实了 PVDF 纳米纤维聚合物在 DSSC 应用中的优异特性和高热稳定性。该研究的重要发现强调了木瓜叶叶绿素色素实现的卓越 DSSC 性能,在不使用聚合物电解质的情况下效率达到 1.31%。此外,在使用聚合物电解质时,山竹叶染料成为效率最高的竞争者,PVDF NF 和 PVDF 的效率分别为 1.17% 和 0.95%,与液态电解质的 1.26% 效率相当。

Characterization and Application of Natural Photosensitizer and Poly(vinylidene Fluoride) Nanofiber Membranes-Based Electrolytes in DSSC
This comprehensive research has explored the potential of enhancing dye-sensitized solar cells (DSSC) by harnessing environmentally friendly natural dyes, such as chlorophyll pigments from pandanus (664.1 nm) and papaya leaves (664.0 nm), as well as betacyanin pigments from sappan-mangosteen (536.2 nm). Electrochemical analyses elucidated the energy band gaps, revealing a hierarchy with the smallest band gap observed for papaya leaves (1.387 eV), followed closely by sappan-mangosteen (1.389 eV) and pandan leaves (1.396 eV). This research effectively addressed the persistent issue of electrolyte leakage in DSSC development by introducing a polymer electrolyte derived from polyvinylidene fluoride (PVDF) through electrospinning and phase inversion techniques. SEM characterization results and thermogravimetric analysis underscored the superior characteristics and high thermal stability of the PVDF nanofiber polymer for DSSC applications. The study's pivotal findings underscore the remarkable DSSC performance achieved with chlorophyll pigment from papaya leaves, reaching 1.31% efficiency without a polymer electrolyte. Moreover, the sappan-mangosteen dye emerged as a promising contender with the highest efficiency values when applied with polymer electrolyte, recording rates of 1.17% for PVDF NF and 0.95% for PVDF, which are notably comparable to the efficiency of liquid electrolyte at 1.26%.
