Abstract:

This document reports on the main activities and outputs originated under this research project over a period of 3 years. The program was targeted at first realizing a molecular photovoltaic cell based on a dye sensitized nanocrystalline semiconductor film employing a hole conductor, a conducting polymer or a polymer electrolyte reaching an AM 1.5 solar-to electric conversion efficiency of at least 2.5 , within the first 9 months itself. This milestone was achieved within 9 months by producing solid-state solar cells containing hole conductors, with 2.56 efficiency. Further, a new type of solar cell based on polymer electrolytes was also developed. A typical cell of this type showed 5.06 solar conversion efficiency. All efficiency figures were certified by NREL, USA. In the second and the third years the aims were to reach conversion efficiencies reaching 5 and 10 respectively and these targets have been achieved. Three annual progress meetings to review the progress of the project have been organized during the project duration.
