DSSC is an acronym that stands for Dye-Sensitized Solar Cell. A DSSC is a type of solar cell that converts solar energy into electrical energy using a process called photovoltaics.
The fundamental structure of a DSSC consists of several key components. The main ones are a semiconductor layer, a dye molecule, an electrolyte, and two electrodes. The semiconductor layer is typically made of titanium dioxide, which acts as a substrate for absorbing sunlight. The dye molecule, often based on organic or inorganic compounds, absorbs specific wavelengths of light and transfers their energy to the semiconductor layer. The electrolyte is responsible for the transport of electrons within the cell, completing the electric circuit. The two electrodes, made of conductive materials like platinum or indium tin oxide, collect and transport the electrons.
The operation of a DSSC involves the absorption of photons by the dye molecule, causing it to become excited. This energy is transferred to the semiconductor layer, where electrons are released and move towards the electrode with opposite charge, creating an electric current. Meanwhile, the dye molecule returns to its ground state to be ready for another photon absorption.
DSSCs have gained attention due to their potential for low-cost production and high efficiency in converting sunlight to electricity, even in diffused light or low-light conditions. They can be flexible, transparent, and even produce electricity from indoor lighting. Although further advancements are still being made to enhance their performance, DSSCs hold promise as a viable option for renewable energy generation.
