Abstract: (1607 Views)
Third generation nanostructure-based solar cells such as dye-sensitized solar cells (DSSCs) are green and low-cost future substitute for silicon-based solar cells. Zn2SnO4-based DSSCs are attractive due to their interesting properties, but aggregated Zn2SnO4 nanoparticles with their limited surface and numerous trap states deteriorate DSSC performance. Electric field assisted sintering (EFAS) due to its outstanding impacts on optical and electrical characteristics can boost DSSC performance. EFAS could manipulate nanostructure matrix remarkably enhanced light harvesting further; this method helps to improve electron transportation by decreasing trap states and increasing recombination resistance. The reported strategy is applicable in numerous electro-optical devices including nanoporous medium such as perovskite solar cells.
Keywords: Zn2SnO4-based dye-sensitized solar cell, Electric field assisted sintering, morphology, surface area, electron lifetime
