由于较大的有机阳离子可以作为天然屏障，二维钙钛矿是增强抗湿性的提议策略之一。然而，二维钙钛矿阻碍了电荷在某些方向上的传输，降低了太阳能电池的功率转换效率。提出了一种纳米结构的混合维方法来克服电荷传输的限制，获得超过9%的功率转换效率。
2D perovskites is one of the proposed strategies to enhance the moisture resistance, since the larger organic cations can act as a natural barrier. Nevertheless, 2D perovskites hinder the charge transport in certain directions, reducing the solar cell power conversion efficiency. A nanostructured mixed-dimensionality approach is presented to overcome the charge transport limitation, obtaining power conversion efficiencies over 9%.
