      In this work we study the optimization of laser-fired contact (LFC) processing parameters, namely laser power and number of pulses, based on the electrical resistance measurement of an aluminum single LFC point. LFC process ...
    • Optimization of laser processes in n+Emitter formation for c-Si solar cells 

      Orpella García, Alberto; Martín García, Isidro; Blanqué, Servane; Voz Sánchez, Cristóbal; Sánchez, I.; Colina, M.; Molpeceres, C.; Alcubilla González, Ramón (2009-09)
      Conference report
      Open Access
      Punctual phosphorus diffused emitters were achieved by laser patterning phosphorus doped a-SiCx:H films deposited by PECVD as a doping source. Two different lasers at wavelengths of 1064 nm and 532 nm were used. Phosphorus ...
    • Optimization of the rear point contact scheme of crystalline silicon solar cells using laser-fired contacts 

      Molpeceres, C.; Perales Lorente, José Francisco; Ortega Villasclaras, Pablo Rafael; Orpella García, Alberto; López, Gema; Martín García, Isidro; Voz Sánchez, Cristóbal; Alcubilla González, Ramón; Sánchez, Isabel; Colina, M. (2010)
