| Abstract |
| Here we present a novel idea with a simple manufacturing method to replace the expensive and not-large-area-applicable Au top electrode in regular n-i-p perovskite solar cells. The proposed electrode consists of a low-cost carbon paper and a conductive adhesive. The electrode is applied to the cell by a simple lamination method. It can resolve the problems of high material and deposition costs and is applicable to large scale production. Additionally, instead of high-cost spiro-OMeTAD which is usually used as hole transport material, we use inorganic CuInS2. Perovskite solar cells fabricated with laminated carbon electrode exhibits open-circuit voltage of 1.08V and efficiency of 7.80% which is not quite far from open-circuit voltage and efficiency of perovskite solar cells with Au electrode which were 1.07 and 10.29%, respectively. Short-circuit current density and fill factor of carbon-based devices are 12.43 mA/cm2 and 0.58 compared to 15.21 mA/cm2 and 0.63 in devices based on Au electrode. |
