电化学沉积的Cu2O太阳能电池由于最近效率加倍而受到越来越多的关注。这是通过在通过原子层沉积来沉积掺杂ZnO层中使用的受控化学环境实现的，原子层沉积不太适合于大规模工业生产。虽然露天制造与大气压空间原子层沉积克服了这一限制，我们发现，这种方法是有限的，无法去除有害的CuO层，形成在CuO表面上。在此，我们提出了在大气处理的电池中实现效率的策略，其相当于在真空处理的电池中实现的高值。(C)2015年作者。除非另有说明，否则所有文章内容均根据Creative Commons Attribution 3.0 Unported License许可。
Electrochemically deposited Cu2O solar cells are receiving growing attention owing to a recent doubling in efficiency. This was enabled by the controlled chemical environment used in depositing doped ZnO layers by atomic layer deposition, which is not well suited to large-scale industrial production. While open air fabrication with atmospheric pressure spatial atomic layer deposition overcomes this limitation, we find that this approach is limited by an inability to remove the detrimental CuO layer that forms on the Cu2O surface. Herein, we propose strategies for achieving efficiencies in atmospherically processed cells that are equivalent to the high values achieved in vacuum processed cells. (C) 2015 Author(s).
