Background
With the continuous development of building integrated photovoltaic, the requirements on the appearance of the photovoltaic module become more stringent. The perovskite, organic and polymer solar cells can be prepared into semitransparent or colored photovoltaic modules, so that the application scenes of building photovoltaics are wide, but opaque bus strips can have little influence on the attractiveness of the semitransparent or colored photovoltaic modules. Therefore, the development of transparent bus bar materials is the focus of research in the future.
Some transparent materials such as indium tin oxide, indium-doped zinc oxide, silver nanowires, carbon nanotubes, and graphene materials are the materials of choice for preparing transparent bus tapes. However, these materials have a great limitation in the application of transparent bus tapes because they cannot achieve a balance between transparency and conductivity and have poor compatibility with substrate materials (polymer, glass), for example, they are difficult to solder for connecting and penetrating circuits and have strong adhesion with glass and polymer substrates.
