一种太阳能电池的新方法

Popping phosphorus into a laboratory microwave is a quick and convenient method for making single-atom-thick sheets of the material, 把磷弹进实验室的微波里是制作这种材料的单原子厚薄片的一种快捷方便的方法research led by Flinders University has shown.

Just like carbon gains super-properties when slimmed down to its 2D form graphene, so does phosphorene, the 2D form of phosphorus. 就像碳在被简化为2D形式的石墨烯时获得了超性能一样，磷也一样，2D形式的磷The material boasts excellent electron mobility, for example, and has been shown to be a powerful electrocatalyst.例如，这种材料具有极好的电子迁移率，并被证明是一种强大的电催化剂。

Now, an Australian research team has shown that phosphorene could boost the performance of dye-sensitised solar cells (DSSCs)染料敏化太阳能电池. Although touted as a potential low-cost alternative to silicon solar cells, DSSCs require the rare and expensive precious metal platinum for one key electrocatalytic component of the cell. 尽管被吹捧为硅太阳能电池的潜在低成本替代品，DSSCs需要稀有昂贵的贵金属铂作为电池的关键电催化成分。

The team has now shown sheets of black phosphorus just a few atomic layers thick, made by microwave-assisted liquid-phase exfoliation, are a promising DSSC electrocatalyst. 研究小组目前已经证明，由微波辅助液相去角质技术制成的黑磷薄片只有几个原子层那么厚，是一种很有前途的DSSC电催化剂The DSSCs they fabricated using this material had a photovoltaic efficiency of 8.31 per cent, outperforming expensive platinum-based cells.他们用这种材料制作的DSSCs的光电效率为8.31%，优于昂贵的铂基电池
