- Abstract
An 11.2% efficient kesterite solar cell is fabricated with a open circuit voltage (Voc ) deficit of only 0.57 V, which is possible by employing the three‐stage annealing process. The reduced Voc deficit goes along with an increased minority carrier lifetime, low diode saturation current, and ideality factor, which are signatures of the semiconductor material with a low concentration of recombination centers.
