A laser photochemical process is introduced to realize superhydrophobic conducting carbon coatings with broccoli-type hierarchical morphology for use as a metal-free counter electrode in a dye sensitized solar cell. The process involves pulsed excimer laser irradiation of a thin layer of liquid haloaromatic organic solvent o-dichlorobenzene (DCB). The coating reflects a carbon nanoparticle-self assembled and process-controlled morphology that yields solar to electric power conversion efficiency of 5.1% as opposed to 6.2% obtained with the conventional Pt-based electrode.
介绍了一种激光光化学反应，用于实现具有类似西兰花形态的超疏水导电碳涂层，用作染料敏化太阳能电池中的无金属对电极。该过程涉及脉冲准分子激光辐照薄层液态卤代芳烃有机溶剂邻二氯苯（DCB）。该涂层反射出由碳纳米粒子自组装和过程控制形态形成的涂层，与传统的基于 Pt 的电极相比，其光电转换效率为 5.1%，而不是 6.2%。
