Although ambient processing is the key to low-cost organic solar cell production, high-vacuum thermal evaporation of LiF is often a limiting step, motivating the exploration of solution processing of LiF as an alternative electrode interlayer. Submonolayer films are realized with the assistance of polymeric micelle reactors that enable LiF particle deposition with controlled nanoscale surface coverage. Scanning Kelvin probe reveals a work function tunable with nanoparticle coverage with higher values than that of bare indium tin oxide (ITO).
尽管环境处理是低成本有机太阳能电池生产的关键，但高真空热蒸发的氟化锂往往是一个限制步骤，这促使人们探索氟化锂的溶液处理作为替代电极夹层的方法。在聚合物胶束反应器的辅助下，可以实现亚单层薄膜，从而可以控制纳米级表面覆盖度来实现氟化锂颗粒的沉积。扫描开尔文探针显示，功函数可以通过纳米颗粒覆盖度进行调节，其值高于裸露的铟锡氧化物（ITO）。
