Abstract

A study was conducted to analyze a novel pseudo one-dimensional architecture for dye-sensitized solar cells (DSSC) photoanodes, which were prepared using templates of low-density, high surface area, mesoporous aerogel thin films. Zno was conformally deposited with a controlled variable thickness on the aerogel templates by atomic layer deposition (ALD). The electrodes incorporated into DSSCs displayed good light harvesting efficiency and excellent power efficiencies compared with other ZnO based DSSCs. The study found that a major limitation to the overall efficiency was mass transport. The excellent initial performance reported in the study, the ease of fabrication, and the flexibility of design also make ALD coated aerogel templated photoanodes a promising candidate to move beyond nanoparticle electrodes in DSSCs.
