Characteristic results of solar cells showing negative capacitance at forward bias:[1,18] a polycrystalline CdTe solar cell, an extremely thin absorber (ETA) cell based on rough TiO2, a dye-sensitized solar cell (defective) with the solid OMeTAD hole conductor, and a normal P3HT/PCBM bulk heterojunction organic solar cell.
