Enhancing the efficiency of silicon based solar cells with bio-based material from algae

Important results from the project

The purpose of the project was to investigate whether the efficiency of a solar cell can be enhanced by applying frustules directly on the surface. This has been verified together with the correlation between efficiency enhancement and applied material. A mapping of the different types of solar cells and their production methods was done in order to evaluate which cell type and production process that should be best suited for the application of frustules.

Expected long term effects

We have been able to verify an efficiency enhancement of the solar cells, but the process has not been optimized due to difficulties in relation to formulation and application of the coating. The results are however very promising and an indication of the potential of applying frustules on the surface of the cells. The ambition level of the project was very high, and the work has created a good base for further investigations.

Approach and implementation

The cooperation between SAFAB and CIT has worked very well where SAFAB has contributed with knowledge related to the material itself together with experiences gained from cooperation with actors in the solar industry. CIT has contributed with expert knowhow related to solar cell manufacturing and contacts with the institute in Norway that has performed the evaluation of the coated cells. Both parties have a good network within the research community which has been utilized during the project.
