The aim of the projects is to improve the scientific qualification of students, researchers and scientists through practical scientific activities. Project activities – developing students’ abilities through research participation.
Project funding:
Project is funded by EU Structural Funds according to the 2014–2020 Operational Programme for the European Union Funds’ Investments priority “Development of scientific competence of researchers, other researchers, students through practical scientific activities” under Measure No. 09.3.3-LMT-K-712.
Project results:
During the work, 1,4,5,8-naphthalenedetracarboxydimides with ammonium and phosphonic acid “anchoring” groups and a di-tert-butylphenyl moiety were synthesized and investigated. In summary, the results obtained showed that not all synthesized semiconductors can function as electron transporting materials due to their poor solubility in organic solvents (Compound 6). The electrochemical and optical properties of naphthalene tetracarboximidides 2 and 4 are suitable for their use in the construction of perovskite solar cells. After studying the thermal properties, it was found that compound 2 with an “anchoring” phosphonic acid group meets the requirements for thermostability. Perovskite solar cells constructed with a naphthalene tetracarboximide 4 monolayer demonstrated 12.14% device efficiency. It has been demonstrated that the monolayer concept works and yields relatively efficient devices, further work should focus on optimizing the device design and monolayer coating technology to further improve the performance of the device.
