An optimal interconnector is obtained using organic heterojunction with n/bulk heterojunction/p structure. It is proven that the interconnector can provide sufficient charge generation and ohmic charge injection. Record power efficiencies of 57.5, 126.8, and 52.7 lm W −1 are achieved for red, green, and blue color tandem organic light‐emitting diodes, respectively, which are enhanced from the corresponding single unit ones.
