We have designed and fabricated high-performance inorganic/organic hybrid tandem solar cells and investigated the effects of interlayer combination and thickness matching on the device performance. The obtained results indicate that the ITO/PEDOT:PSS interlayer can provide an efficient recombination region for electrons and holes generated from the top and bottom cells, owing to the formation of superior ohmic contacts. Furthermore, the optical transmission through the bottom inorganic solar cell was optimized to maximize the optical absorption of the top organic solar cell. The power conversion efficiency of the optimized hybrid tandem solar cells reached a maximum PCE of 5.72% and the measured Voc was 1.42V, reaching 92% of the sum of the subcell Voc values. This study opens up a new direction towards the achievement of a universal optimal device layout and provides the potential to further enhance the efficiency of future hybrid tandem solar cells. |
