Highly stable semi-transparent CH3NH3PbI3 sandwich type perovskite solar sub-module with neutral color |
| 초록 |
~10% semi-transparent neutral color sandwich type CH3NH3PbI3 (MAPbI3) perovskite sub-module (active area = 25 cm2) with UV cross-linked polystyrene passivation layer showed ~2.8% degradation of initial efficiency after continuous light soaking of 1 Sun for 1000 h at 55°C. Due to the role of islandmorphology-MAPbI3 as selective UV-cut mask, the UV curable monomeric compounds on the islandmorphology-MAPbI3/blocking TiO2/F-doped tin oxide substrate could be selectively cross-linked polymerized by exposure of UV light and consequently the UV cured passivation layer could be reproducibly deposited in the gaps between perovskite islands after simple washing of unreacted residue. The degree of cross-linking was controlled by adjusting the concentration cross-linker in the UV curable monomeric compounds from eventually 5 mol% sample showed the best power conversion efficiency of 11.58% for forward scan condition and 11.95% for reverse scan condition. |
