The Solar Energy Group (2009 SGR 1532) of the University of Barcelona is mainly focused in the developement of new technologies for photovoltaic modules based on silicon thin films. These include modules based on p-i-n structures of amorphous and microcrystalline silicon and on heterojunction silicon solar cells.

The group is working in the developement of hot-wire chemical vapor deposition (HWCVD) for the silicon-based materials. Activities in the field of transparent conducting oxides and light confinement strategies for using in thin film silicon solar cells are also being carried out.

Finally, the group carries out the monitoring of the parameters of photovoltaic modules under real conditions, and other parameters such as irradiance or temperature, with the aim to elaborate realistic models for thin film silicon modules that could be useful for the design of photovoltaic systems.
