Abstract

The current state-of-the-art perovskite solar cell (PSC) reaches a certified power conversion efficiency of 24.2%. However, one of the main drawbacks of PSCs is their stability. The use of compositional engineering based on the combinations of anions and cations of the perovskite structure gives good results in terms of efficiency and stability. Guanidinium (GA) is successfully investigated as an additive in the MAPbI(3) perovskite, improving structure, performance, and midterm stability. Similarly, among the cations that can form a 3D perovskite structure, imidazolium (IA) shows a large and favorable ionic radius (258 pm), in the upper limit of the tolerance factor. Herein, the stability and performance of perovskite-based solar cells is studied when the methylammonium (MA) cation is gradually replaced with an IA cation in the precursor solution. Mixed MA/IA perovskites (MA(1 - x)IA(x)PbI(3)) are characterized by studying the effects of the IA incorporation on optoelectronic properties, film morphology, and crystal structure. X-ray diffraction analyses establish the limit of solubility of IA at about 10%, and MA(1 - x)IA(x)PbI(3) perovskites with an IA content of 6% show an improvement in crystallinity. Also, a study on the midterm stability of the mixed MA/IA perovskite is presented.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-03:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 9.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 9 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).
