Perovskite solar cells have increased rapidly to the efficiency, starting with an efficiency of 3.9% in 2009. In order to increase the efficiency of perovskite solar cells, various defects must be reduced or eliminated. One way to easily reduce such defects is the additive process. By using additives, it is possible to passivate the defects of the perovskite surface and grain boundary. Also, it has positive effects on the grain and is involved in increasing the grain size. Here we chose to coat on the perovskite layer so that the additives effects can be more focused on the surface passivation. We study to increase the efficiency and stability of perovskite solar cells by using additives with various functional groups. We will investigate how the functional groups of additive effect perovskite. |
