Dye-sensitized solar cell efficiency has been raised to a record 15% thanks to a new fabrication process developed by EPFL scientists.
Dye-sensitized solar cells (DSSCs) have many advantages over their silicon-based counterparts. They offer transparency, low cost, and high power conversion efficiencies under cloudy and artificial light conditions. However, until now their overall efficiency has been lower than silicon-based solar cells, mostly because of the inherent voltage loss during the regeneration of the sensitizing dye. In a Nature publication, EPFL scientists have developed a state solid version of the DSSC that is fabricated by a new two-step process raising their efficiency up to a record 15% without sacrificing stability.
The new solid-state embodiment of the DSSC uses a perovskite material as a light harvester and an organic hole transport material to replace the cell’s electrolyte. Typical fabrication of this new DSSC involves depositing a perovskite material directly onto a metal-oxide film. The problem is that adding the entire material together often causes wide variation in the morphology and the efficiency of the resulting solar cell, which makes it difficult to use them in everyday applications.
Michael Grätzel‘s team at EPFL has now solved the problem with a two-step approach: First, one part of the perovskite is deposited in to the pores of the metal-oxide scaffold. Second, the deposited part is exposed to a solution that contains the other component of the perovskite. When the two parts come into contact, they react instantaneously and convert into the complete light-sensitive pigment, permitting much better control over the morphology of the solar cell.
