      Calvet Roures, Iván; BARRACHINA ALBERT, ESTER; Martí Valls, Rafael Francisco; Fraga Chiva, Diego; Lyubenova, Teodora; Carda Castelló, Juan Bautista Elsevier (2015)
      Ceramic photovoltaic tile based on Cu2ZnSn(S,Se)4 semiconductor has been made by low-cost and easy processing method of preparation. Ceramic tile as alternative of soda-lime glass substrate has been used. The molybdenum ...
    • openAccess   Effect of Al, Ga, and In Doping on the Optical, Structural, and Electric Properties of ZnO Thin Films 

      Porcar García, Samuel; González Cuadra, Jaime; Fraga Chiva, Diego; Stoyanova Lyubenova, Teodora; Soraca, Gina; Carda Castelló, Juan Bautista MDPI (2021-11-01)
      ZnO thin films with oxygen vacancies and doped with Al, Ga, and In (Zn1-xMxO1−y (x = 0.03)) have been successfully deposited on soda-lime glass substrates using a simple soft chemical method. The crystalline structure shows ...
    • openAccess   Enhanced Electrical Properties of Alkali-Doped ZnO Thin Films with Chemical Process 

      González Cuadra, Jaime; Porcar García, Samuel; Fraga Chiva, Diego; Lyubenova, Teodora; Carda Castelló, Juan Bautista MDPI (2021)
      Doped ZnO are among the most attractive transparent conductive oxides for solar cells because they are relatively cheap, can be textured for light trapping, and readily produced for large-scale coatings. Here, we focus on ...
