Enhancing Open‐Circuit Voltage in Gradient Organic Solar Cells by Rectifying Thermalization Losses

Beyond Langevin Recombination: How Equilibrium Between Free Carriers and Charge Transfer States Determines the OpenCircuit Voltage of Organic Solar Cells

However, they have low open-circuit voltages and typically cannot be made optically thick while maintaining high fi ll factors. [ 4,5 ] For comparison, the best silicon solar cell has a bandgap of 1.1 eV and an open-circuit voltage of 0.71 V, corresponding to a difference between the bandgap and qV oc of only 0.40 eV. [ 1 ] In contrast, one of the best performing organic solar cells, PTB7:PC 71...

Interface Engineering of Organic Schottky Barrier Solar Cells and Its Application in Enhancing Performances of Planar Heterojunction Solar Cells

In this work, we describe the performance of organic Schottky barrier solar cells with the structure of ITO/molybdenum oxide (MoOx)/boron subphthalocyanine chloride (SubPc)/bathophenanthroline (BPhen)/Al. The SubPc-based Schottky barrier solar cells exhibited a short-circuit current density (Jsc) of 2.59 mA/cm(2), an open-circuit voltage (Voc) of 1.06 V, and a power conversion efficiency (PCE) ...
