A flexible photoelectric device module and a method for preparing same are provided. The module includes a plurality of photoelectric device units. One photoelectric device unit includes a bottom electrode, a functional layer and a top electrode. The bottom electrode includes a light-transmittance insulating base, and a first electrode, a second electrode and a third electrode which are arranged on two side surfaces of the base. The first electrode is a transparent electrode. The second electrode and the first electrode are in electric contact with each other. The second electrode and the third electrode are electrically connected through a conducting channel. The conducting channel runs through the base along a thickness direction. The third electrode in one photoelectric device unit is electrically connected to the top electrode or the first electrode in another photoelectric device unit, so that the two photoelectric device units are disposed in series or in parallel.

The disclosure discloses an organic photoactive layer composite ink, an organic solar cell and preparation methods thereof. The organic photoactive layer composite ink includes an electron donor material, an electron acceptor material, an organic amine compound and an organic solvent. According to the disclosure, through an interaction between the organic amine compound and a photoactive layer material molecule, the photochemical reaction of the active layer molecule can be effectively inhibited, the photostability of the photoactive layer material is significantly improved, and hence the stability of the solar cell is greatly improved. The organic solar cell prepared by the disclosure has the advantages of high stability, long use service life and the like, and working properties such as energy conversion efficiency are also effectively improved; meanwhile, the organic solar cell is simple and convenient in preparation process, low in material cost and high in economic benefits.
