Solar energy is currently one of the main sources of clean energy and its importance has been growing up steadily in the last decades. Computational simulation of wave propagation in solar cells is crucial for the development of new photovoltaic devices. Modern solar cells embed complex multi-layer geometries that must be taken into account properly in numerical simulations. The new generation of parallel computers provides the necessary computational power to handle realistic three-dimensional wave propagation phenomena in complex multi-layer photovoltaic devices.
Nevertheless, numerical methods must be revisited entirely to take full advantage of such new parallel facilities. The PHOTOM project aims at developing, analysing and implementing innovative multiscale finite element numerical methods method for wave propagation models in grating media motivated by its use in the simulation of photovoltaic solar cells.
The PHOTOM project corresponds to a two-year international collaboration between universities and research laboratories from Brazil, Chile and France. Contribution of each participating institution are the following:
