Enhanced light absorption of thin perovskite solar cells using textured substrates

Jingshan Luo

Thin perovskite layers are crucial for fabricating semitransparent perovskite solar cells and tandem devices. However, this will reduce the light absorption of the device, resulting in low efficiency. To overcome this dilemma, we use textured fluorine dope ...
