Enhanced light absorption of thin perovskite solar cells using textured substrates
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 doped SnO2 (FTO) substrates to trap light and en...

| description | 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 doped SnO2 (FTO) substrates to trap light and enhance light absorption in thin perovskite solar cells. Both optical simulation and experimental demonstration show the successful application of this new strategy in enhancing the efficiency. In the meantime, the transmittance of the full cell beyond the perovskite absorption range is not sacrificed, which is pivotal for fabricating semitransparent perovskite solar cells and tandem devices.
Textured substrate prolongs diffusion length of photon for better light absorption and thus better JSC of perovskite solar cells. [Display omitted]
•Light trapping within perovskite absorber is introduced by textured conducting substrate.•Textured substrates endow perovskite layer with uniform, compact and large crystal grains.•Enhanced light absorption in textured film lead to better JSC and η of perovskite solar cells.•This work shines the light on preparing efficient tandem or semitransparent solar cells. |
