Dye Sensitized Solar Cell: A Summary

Dye sensitized solar cell (DSSC) devices incorporating organic and inorganic materials have found a host of applications. The search for low-cost, high efficient and flexible devices has lead to a remarkable increase in the research and development of solar cell. The current review, describes the constitution components of DSSC in a detailed manner and their development and challenges are also discussed. We focused on various structural modifications in wide band gap nanocrystalline semiconductor materials for an efficient electron transfer to reduce the recombination rate. Fruitful attempts have been made to design new molecular dyes for the wide range of absorption in the visible region. Co-Sensitization is an appropriate technique to enhance the absorption range of dye molecules and to increase the efficiency of solar cell. Moreover hole transport materials, there are the efficient tool to replace redox couple based liquid electrolyte and it produce stable solid state DSSC. The successful modification of counter electrode with different morphology promotes the rate electron transfer into electrolyte. This review also covers the update technology to construct efficient, stable and flexible dye sensitized solar cell.
