RT Book, Section T1 The intermediate band approach in the third solar cell generation context A1 Martil De La Plaza, Ignacio A1 García Hemme, Eric A1 García Hernansanz, Rodrigo A1 González Díaz, Germán A1 Olea Ariza, Javier A1 Prado Millán, Álvaro Del A2 García, Héctor A2 Castán, Helena AB Within the framework of the third solar cell generation some new ideas to enlarge the spectral response of the solar cells toward the infrared have been proposed. Among them the inclusion of an Intermediate Band (IB) seems to be very promising. This paper will deal with one of the ways to generate the IB namely the deep level center approach. We will discuss not only its existence but also the carriers lifetime recovery which is necessary to obtain the expected increase of the solar cell efficiency.
