Silicon solar cells are instrumental in transforming solar energy into electrical energy. The efficiency of this cell is based on the purity of silicon, making it expensive. The fragile And the production process, the impact on the environment. It is designed dye-sensitized solar cells up to be an alternative for people who want solar cells that are cheaper because the production process is not complicated. Materials used to make dyes can also be obtained from nature. It does not affect the environment. In this research study on solar cells, dye sensitized to extract from nature, including Roselle pea flowers and a hybrid (Roselle and Crake) under production conditions are different, including itself. is solvent Water and ethanol The color temperature of the extraction was 25, 50, 70 and 100 degrees Celsius and the pH was 0.5, 1.0, 2.0 and 3.0, then test the absorbance of the dye-sensitized extracted. And test the conversion efficiency of solar energy into electrical energy to dye makes a good and reasonable to the production of solar cells, dye-sensitized solar cells with efficiencies comparable to silicon development is also sensitive dyes. Better light quality Suitable for solar cells to replace silicon.
