Review on Dye-Sensitized Solar Cells (DSSCs)

Our planet’s community largely depends on a snug energy supply, and non-renewable energy such as fossil fuel has been serving as the most trustworthy energy source from its discovery time of 1673 till to the current century. However, non-renewable energy resources are rapidly decreased per year due to increasing the energy consumption rate. To address this issue, renewable energy chiefly photovoltaic energy has attracted much though, because it directly converts solar energy into electrical without environment pollution. For the past several years, different photovoltaic devices like inorganic organic, and hybrid solar cells are invented for different application purposes. Regardless of its high conversion rate of silicon based solar cells, the high module cost and complicated production process restricted their application. Research has been focused on alternative organic solar cells for their inherent low module cost and easy fabrication processes. From all organic solar cells, Dye-Sensitized Solar Cells (DSSCs) are the most efficient, low cost and easily implemented technology. This review paper focus on clarifying the technological meaning of DSSCs, Types of DSSCs materials, working principle, advantages, power full applications area of DSSCs, the efficiency and challenges for R&D of DSSCs to upgrade the current efficiency.
