Project Title: Printable ionic-gel electrolyte for highly durable dye sensitized solar cells (DSSC)

Applicant:Dr. Tony Shien-Ping FENG, Department of Mechanical Engineering, The University of Hong Kong

Total Approved Grant: $489,000 (ECF & WWGF: 50/50)

Duration: 1/4/2015 to 31/3/2017

Project Status/Remarks: On-going

As a promising alternative for next generation of renewable green energy, dye-sensitized solar cells (DSSCs) have attracted great attention due to their low cost, environmental friendliness, simple fabrication, great potential of miniaturization and portability, as well as the recent high power conversion efficiency. However, the long-time stability of DSSCs remains a road block for their widespread use. This project aims to develop a clay-like ionic-gel electrolyte paste to improve the long term stability of DSSCs. The amount and type of inorganic nano-powders adding into ionic electrolyte will be studied to improve the conductance of electrolyte. Different surface treatments for nano-powders to make a homogeneous dispersion will be investigated. The fundamental conductive behaviour at interface between nanoparticles and gel will be modelled and discussed. The printing process will be developed for this printable ionic-gel electrolyte.
