Long Term Stability of Dye sensitized Solar Cells for large area power applications

Objective



Objectives of the Project
To be able to commercialise the Dye Sensitized Solar Cell (DSC) technology for large area power applications it needs to be clear what module life-times and efficiencies can be obtained. Therefore, there are two main objectives to this project:
- To demonstrate that a 10 year outdoor module life-time is feasible. - To demonstrate that a module efficiency of 10% is theoretically feasible.
Technical Approach
The approach for the stability part is to start with simple, individually available stability tests of state-of-the-art devices. During the project new test procedures will be developed, especially suitable for DSC's, based on accelerated solar aging, transient response, thermal cycling and hot-spot illumination. The effect of the state-of-the-art cell components, component interactions and fabrication procedures on the stability will be visualised by extended characterisation (chemical, spectroscopic, electrochemical and solar cell characterisation methods). Improved components and fabrication methods will be developed and tested for stability. This will be implemented into devices, whose stability will be compared with earlier results. The approach for efficiency part is to reproduce literature laboratory efficiencies up to 10% for small area single-cell devices. Based on theory and experimental results, including advanced characterisation of devices and components a model will be developed to separate the various contributions of the cell components to the output characteristics. Experiments and model will result in knowledge about the maximum obtainable laboratory single cell efficiency. Combined with data on module design and module components a realistic estimation of theoretically feasible module efficiencies can be given.
Expected Achievements
At the end of the project, the expected achievements related to stability are: - DSC appropriate accelerated testing procedures are worked out. - The feasibility of a life time of over 10 years is demonstrated. - The components and processes to obtain stable devices are known. At the end At the end of the project, the expected achievements related to efficiency are:
- A laboratory device (single cell) with an efficiency of 10% on an area of 1 cm2.
- A computer model describing the contributions of the various cell components to the electrical behaviour.
- Knowledge about the maximum obtainable laboratory and module efficiencies.
