Abstract

A light-sensitive coloring agent as a ruthenium metal complex which is shown as the formula (1).

Description

technical field [0001] The present invention relates to a solar cell material, and in particular to a photosensitive dye applicable to dye-sensitized solar cells (DSCs). Background technique [0002] "Energy" has become one of the important issues that people are actively developing and solving. However, in addition to the depletion of petrochemical energy currently relied on, the excessive use of petrochemical energy has also brought serious pollution problems. Therefore, the development and application of low-pollution renewable energy will become the only way for human beings to seek sustainable development. At present, the sources of renewable energy can be roughly divided into: solar energy, wind power, hydraulic power, tidal power, geothermal energy, and biomass energy. Among the many types of energy, solar energy is the most valued. The reason is that this type of energy is the most abundant and its development and application are not restricted by terrain, landform ...
