Deep-blue electroluminescence with a maximum EQE of 5.74% and CIE<sub>y</sub> ∼ 0.05 is achieved based on newly designed D–π–A fluorophore HLCT excited state.
Although the power conversion efficiency values of perovskite solar cells continue to be refreshed, it is still far from theoretical Shockley-Queisser limit. Two major issues need addressed, including disorder crystallization and unbalanced interface charge extraction, which limit further improvements in device efficiency. Herein, we develop a thermally polymerized additive as polymer template film, can form monolithic grain unique "Mortise-Tenon" structure after spin-coating hole-transport...
