Although the price of dye-sensitized solar cells is lower than other solar cells, they still contain some high-cost materials, such as transparent conductive substrates, dyes (ruthenium dyes, organic dyes, etc.), and platinum counter electrodes. To solve this problem, a dye-sensitized solar cell based on hibiscus leaching solution and carbon black–silver electrodes was prepared by screen printing. The prepared low-cost dye-sensitized solar cells were flexible. The open-circuit voltage (Voc) of the obtained dye-sensitized solar cell is 0.65 V, the current density (Jsc) is 90 μA/cm², and the fill factor (FF) is 0.241.
Porous carbon layers for counter electrodes in dye-sensitized solar cells: Recent advances and a new screen-printing method Paper based on a presentation made at the International Conference on Nanomaterials and Nanotechnology (NANO-2010), Tiruchengode, India, 13–16 December 2010. Other presentations are published in this issue, pp. 1971–2113.
