| titleOfInvention | Method for preparing Perovskite Solar Cell with surfaced-modified hole transportation layer |
| abstract | The present invention relates to a method of manufacturing a perovskite solar cell having improved crystallinity and photoelectric efficiency of a perovskite layer by modifying the surface of a hole transport layer with a hydrophobic organic polymer. The solar cell of the present invention improved the crystallinity of the perovskite layer and the photoelectric efficiency of the device by modifying the surface of the hole transport layer with a hydrophobic organic polymer (PTB7 or PTB7-Th). When PTB7, which is a hydrophobic organic polymer, is used as the main material of the hole transport layer or as an additive in the hole transport layer, a discontinuous perovskite film is formed due to its hydrophobic properties. mL) of a hydrophobic organic polymer is formed on the hole transport layer and then the perovskite precursor is spin-coated to obtain a uniform and large particle size perovskite crystal layer. The solar cell of the present invention not only increased the photoelectric conversion efficiency to 18.43%, but also increased hydrophobicity and maintained 81% of the initial PCE value even after 300 hours. |
