En un estudio que pretende determinar cuáles son las incidencias de la Investigación Formativa sobre la educación andragógica surge la interrogante planteada.
In several papers I found that the optimized band gap for solar cells is close to 1.5 eV. This value corresponds to a wavelength of about 830 nm, in infrared. Is it due to the fact that we use...
