| Popis: |
Organic–inorganic hybrid perovskites have emerged as a promising light absorber for the solar cells due to their remarkable optoelectronic properties. The high-efficiency perovskite solar cells (PSCs) mainly employ the sandwich architecture in which the perovskite active layer is sandwiched between two selective contacts. However, there is an inevitable optical loss in sandwich structures when the light propagates through the transparent conductive substrate and selective contact layer. In order to prevent the transmission loss, novel designs of back-contact structures are demonstrated for the light illumination upon the perovskite. To achieve the back-contact structure, the selective contact and electrode are deposited and patterned on the substrate. The perovskite light absorber is finally deposited on the top of patterned electrode to complete the back-contact device. The photogenerated carriers (hole and electron) are transported in the same direction and extracted by the selective contacts. In this chapter, we summarize recent advances in the back-contact perovskite solar cells (BC-PSCs). |
