Highly mismatched alloys to implement multiband solar cells (HIMAMIS)
Start date: Mar 21, 2013, End date: Oct 29, 2015 PROJECT  FINISHED 

As it is well-known, it is a fact that one of the biggest problems that concern the current world is relative to the high energy consumption. This proposal is relative to the solar cell, in special with the third generation. This new generation of solar cells is created to obtain high efficiency and low cost conversion devices. Therefore, they are a potential component for the future. The proposal presents the know-how for the design, growth and improvement of the multiband solar cell. So far, this kind of solar cells are a specific topic of the Renewable Energies in the European Union Seventh Framework Program (FP7). However, despite a considerable effort of many research groups, there was no evidence of a working multiband photovoltaic device. Recently, the applicant, within a group at the Lawrence Berkeley National Laboratory in the USA, has designed, grown, tested and demonstrated the first multiband device, growing by dilute nitrogen, and being this concept the transfer technology relate to this proposal. Relying on the technological capabilities of the host institution, its deep knowledge on nanotechnology and its recent activities on new efficient solar cells, the new incorporated know-how will boost the activities of host institution to the topmost frontier of knowledge and development within the solar energy field.
