Mártil de la Plaza, Ignacio ; González Díaz, Germán ; Olea Ariza, Javier ; Prado Millán, Álvaro del | American Institute of Physics | 2011-06-01We have analyzed the structural and optical properties of Si implanted with very high Ti doses and subsequently pulsed-laser melted (PLM). After PLM, all samples exhibit an abrupt and roughly uniform, box-shaped Ti profile, with a concentration [...]![]()

Mártil de la Plaza, Ignacio ; González Díaz, Germán ; Olea Ariza, Javier ; Prado Millán, Álvaro del | IOP publishing ltd | 2013-12In this work we present the manufacturing processes and results obtained from the characterization of heterojunction with intrinsic thin layer solar cells that include a heavily Ti ion implanted Si absorbing layer. The cells exhibit external cir[...]![]()

Mártil de la Plaza, Ignacio ; García Hemme, Eric ; García Hernansanz, Rodrigo ; González Díaz, Germán ; Olea Ariza, Javier ; Prado Millán, Álvaro del | IEEE | 2013Within 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. [...]![]()

Mártil de la Plaza, Ignacio ; González Díaz, Germán ; Prado Millán, Álvaro del | AVS Amer. Inst. Physics | 1999-07We analyze the influence of rapid thermal annealing on Al/SiNx:H/Si structures with a nitrogen to silicon ratio of 1.55 in the insulator bulk. The SiNx:H is deposited by the electron cyclotron resonance plasma method and the films were annealed [...]![]()

Mártil de la Plaza, Ignacio ; González Díaz, Germán ; Prado Millán, Álvaro del | American Institute of Physics | 1999-08-15We analyze the effect of thermal processes on the optical properties (refractive index, optical gap, Tauc coefficient, and Urbach energy) of SiNx:H films. Films with three different nitrogen to silicon ratios (x = 0.97, x = 1.43, and x = 1.55, r[...]![]()
