Authors Lioz Etgar 1 , Peng Gao, Zhaosheng Xue, Qin Peng, Aravind Kumar Chandiran, Bin Liu, Md K Nazeeruddin, Michael Grätzel. An electron transporting layer (ETL) plays an important role in extracting electrons from a perovskite layer and blocking recombination between electrons in the fluorine-doped tin oxide (FTO) and holes in the perovskite layers, especially in planar perovskite solar cells. If the numbers changed you successfully made a working solar cell! Be careful not to touch it. A dye-sensitized solar cell (DSSC, DSC, DYSC or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells. This dye-sensitized solar cell, also known as a Grätzel cell, uses a thin film of titanium dioxide which has been ground to a fine powder (nanocrystalline) to increase its reactive surface area. Subscribe Subscribed Unsubscribe 21. Lift the slide out of the juice using tweezers. The film should be stained bright purple/pink. Finally, the space between the slides is filled with a liquid electrolyte solution of potassium iodide which serves to transport charge (by way of a redox reaction) from the bottom electrode to the dye to complete the circuit. The Grätzel cell is has been the focus of years of research but has failed to become a commercial success.

What will be effect on efficiency and life of Solar cell by using these materials. Try other types of berries, synthetic dyes or food colorings. The TiO2 is impregnated with some kind of colored dye, in this case anthocyanin from raspberry juice, which is the chemical which first traps the solar energy and passes the charge to the TiO2. Make sure that all the stained area is wetted with this solution. Orient the strips so that are on opposite sides as shown. Solar cell sensitized by only CdS exhibits a short-circuit photocurrent density (J SC) of 5.7 mA/cm 2 and an open-circuit voltage (V OC) of 0.39 V. On the other hand, solar cell sensitized by only PdS present a poor photovoltaic performance with very low J SC and V OC.
