Marie Curie Research Project

Title of the Project: SnS PV Cells

• Project duration: 2 Years
• Project  Investigators: Prof R W Miles, Prof K T Ramakrishna Reddy
• Start Date: 1st February 2011

Awarding agency:

Research Executive Agency, European Commission, Brussels.
Seventh Framework Programme - Grant Agreement No.: 251802

Objectives of the Project:

• Preparation of conformal and pinhole free SnS films by evaporation/sulphidisation of tin layers using various deposition conditions
• Optimisation of the deposition conditions for obtaining uniform, pinhole free and polycrystalline SnS layers
• Development of highly efficient SnS-based thin film heterojunctions and the evaluation of the junction solar cell performance.
• Economic and environmental analysis of the SnS layers
