layer proximal to the bottom interface is higher than those present in other regions. Consequently, the bottom interface material must exhibit high carrier mobility and conductivity, alongside energy levels that are compatible with the perovskite film to prevent carrier aggregation and recombination [25,...
Thus, the invention provides, among other things, a two-part epoxy-based structural adhesive comprising a curable epoxy resin, an amine curing agent, a toughening agent and a reactive liquid modifier. Various features and advantages of the invention are set forth in the following claims. ...
