Nonradiative Voltage Loss In article number 2000255 , Yasunari Tamai and co‐workers explore highly luminescent organic solar cells. When charge transfer (CT) and local excited (LE) states are very close in energy, a hybrid LE‐CT state is formed. Once the hybrid state is formed, the oscillator strength of the CT state is considerably enhanced, resulting in reduction of nonradiative voltage loss down to 0.185 V.
