The objective of the project PECSYS is the demonstration of a system for the solar driven electrochemical hydrogen generation with an area >10 m². The efficiency of the system will be >6% and it will operate for six month showing a degradation below 100 cm²) and will be subject to extensive stability optimization. Especially, the use of innovative ALD based metal oxide sealing layers will be studi ...

Advanced Gratting for Thin Films Solar Cell (AGATHA)

Date du début: 1 sept. 2010, Date de fin: 31 août 2016,

"The minority carrier diffusion lengths are small in polycrystalline or amorphous materials used in thin film solar cells, requiring thin layers to maximize charge collection. This is contradictory for the requirement to maximize solar energy absorption. The optical design consisting in increasing solar cell’s light-trapping capability is of prime importance. In order to provide total internal ref ...

 TERMINÉ 
In recent years, the effort in thin-film silicon (TFSi) was made at solving industrialization issues. In 2010, several companies demonstrated 10% stable modules (> 1 m²). The major “bricks” for efficient production are now in place. Next challenges are linked to the fact that TFSi multi-junction devices, allowing for higher efficiency, are complex devices, in which the substrate geometry and each ...
