Performance improvement of modified dye-sensitized solar cells

Considering increasing energy demands, it is still a challenge to find finite resources of alternative energy. Owing to their wide range of applications, transparency, simple structure, and low cost, dye-sensitized solar cells (DSSCs) have been extensively studied as one of the most promising new generation silicon-based solar cells. During last decade, tremendous research efforts have been invested to improve the efficiency of solar energy conversion of DSSCs. In this review, we overview various strategies that lead to better performance and stability of the fabricated cell. Recent challenges associated with nanostructured electrodes, device layer structure design, types of dyes and electrolytes with DSSCs performance were studied and discussed.
