| dc.title | Manipulating crystallization process with functionalized additives for high-performance perovskite solar cells in large scale | en_US |
| dcterms.abstract | The Perovskite Solar Cells (PSCs), which has the advantages of inexpensive to obtain, easy to be manufactured and significant efficiency, have been regarded as a technology with a promising future for the photovoltaics. Its remarkable performances lead to massive amount of investment flooding into the research of this new technology. The Hole transporting layer (HTL) plays an decisive part in the extraction and transport of holes, surface passivation, perovskite crystallization, device stability, and cost of the device. Nowadays, HTL is still a great limitation for the overall device performances, researchers are still searching for ways to optimize the structure of HTL to achieve better device performances. | en_US |
| dcterms.abstract | In this dissertation, we firstly discuss the method of combining different kinds of self-assembled monolayer (SAM) materials into the perovskite layers. SAM formers such as 2PACz ((2-(9H-carbazol-9-yl)ethyl)phosphonic acid) and MeO-2PACz (2-(3,6-Dimethoxy-9H-carbazol-9-yl)ethyl)phosphonic acid ) have improved the efficiency of perovskite solar cells (PSCs). [1] The use of Me-4PACz self-assembled monolayer as the hole transporting layer can also enhance the performance of the perovskite solar cells (PSCs). [2] However, all of these materials has a relatively low perovskite wetting ability due to the perovskite solvent can not interact fluently with the SAM layer below. By combing SAM into the perovskite layer, this co-solvent system manage to solve the solution wettability issues. | en_US |
| dcterms.abstract | Secondly, we study the method of combing the 2D material into the perovskite layer to create 2D perovskite, which can be helpful for the large-scale manufacture since it can help solve the stability problems of the PSCs by manipulating the crystallization process of perovskites. | en_US |
