摘要

全固化是染料敏化太阳能电池(DSSCs)实现商业应用的唯一途径。目前，基于空穴输运材料的DSSCs的气相沉积等复杂而昂贵的方法不适合大规模全固态器件的开发。本文提出了将I−/I3−氧化还原对溶解在商用UV胶中，然后在紫外光下固化为电子传输材料的全固态DSSCs的发展新途径。该器件不仅表现出优异的稳定性(功率转换效率(PCE)在1000 h后可保持95%以上)，而且获得了6.15%的最佳PCE(短路光电流密度= 11.93 mA cm−2，开路电压= 683 mV，填充因子= 0.75)。它必然是未来全固态DSSC器件发展的最佳选择。

Development of High-Performance UV Solidification All-Solid-State Dye-Sensitized Solar Cells

All solidification is the only way for dye-sensitized solar cells (DSSCs) to achieve commercial application. At present, the intricate and expensive approaches such as vapor deposition used for DSSCs based on hole transport materials are unsuitable for the development of large-scale all-solid-state devices. Herein, a new avenue for the evolution of all solid-state DSSCs through dissolving the I⁻/I₃⁻ redox couple in commercial UV glue and then solidifying under UV light as electron transport materials is put forward. Not only does this device show superior stability (the power conversion efficiency (PCE) can be maintained more than 95% after 1000 h), but also an optimum PCE of 6.15% (short-circuit photocurrent density = 11.93 mA cm⁻², open-circuit voltage = 683 mV, fill factor = 0.75) is obtained. It must be the best choice for the future development of all-solid-state DSSC device.
