“…CZTSSe powder was fabricated using a modified precipitation method described previously for CIGS absorber layer [40][41][42][43]48 . The process is divided on three-stages: 1) precipitation of metal selenites; 2) paste preparation and deposition and 3) thermal treatment and kesterite crystallization.…”

Abstract:An easy method to obtain kesterite Cu2ZnSn(Se1-x,Sx)4 (CZTSSe) solid solution as an absorber for thin film photovoltaic solar cells is discussed in this report. Particular emphasis is directed toward the procedure´s steps of the CZTSSe preparation, as well as its structure and properties. For the preparation of CZTSSe an easy, low-cost and sustainable aqueous precipitation method that included chemical transformations of metal selenite precipitate, its reduction to metal selenides and further crystallization of kesterite, is applied. This procedure is more viable as avoids the use of selenization treatment and thus generation of toxic vapors and employs water as a solvent instead of organic compounds. In addition, the proposed procedure is very attractive way of preparation for industrial large-scale fabrication of the most promising absorber candidates for photovoltaic thin film solar cells.Kesterite CZTSSe solid solution has been prepared and characterized in terms of chemical composition, structural and morphological transformations, as well as optical and electrical properties, confirming the viability and effectiveness of the applied process.The optimal electrical parameters obtained of the device are 21.5 mA/cm2, 532 mV, 42.8%., and 4.9% to short circuit current (Jsc), open circuit voltage (Voc), fill factor (FF), and efficiency (Eff.) respectively. Detailed description of each procedure steps and full characterization of the products, starting from as-prepared, intermediate and final compound is also exposed that could be very useful for any experimental scientist.2

In this work the use of porcelain stoneware tiles as alternative substrates for CIGS thin film solar cells for the development of specific applications as those related to building integration (BIPV, BAPV) are reported. Two types of porcelain stoneware have been compared: the conventional tile (STD) and the ecological tile (ECO). The ECO ceramic paste formulation has been designed adding industrial wastes (recycled glass, sludges and chamote). Chemical, technological and functional properties of the paste have been performed. The CIGS absorber has been synthesized by an easy and low-cost way of preparation using co-precipitation method. The solar cell device has been completed and fully characterized.The achieved results indicate better performances for ECO paste compared to the STD, stated in improved mechanical resistance, thickness and morphology. It is demonstrated 2 that both tiles are suitable for solar cell applications, but ECO substrate developed higher energy conversion efficiency of 1.3 %.

“…Estos métodos consisten en la síntesis del compuesto de interés en forma de polvo, seguido por su deposición en forma de capa a través de técnicas como Dip-coating, Spin Coating [105,126] o Dr Blade [130] para finalmente aplicar un tratamiento térmico que aumente la cristalización del compuesto. A diferencia de los tratamientos térmicos para CIGS, en los cuales no es un factor limitante la formación de MoS(e) 2 , en estos se trata de maximizar la cristalización de la fase kesterita minimizando la formación de esta interfase, ya que, esta presenta efectos nocivos relacionados con la formación de fases secundarias que afectan a la obtención de la estructura (como se ha explicado con anterioridad en el apartado del band GAP).…”

“…Por otro lado, también se han usado como sustratos cerámicos no flexibles, basados en azulejos cerámicos tradicionales, con el fin de generar un sustrato resistente a altas temperaturas y con facilidad de integración arquitectónica (BIPV) [130]. La versatilidad de composición que ofrece el esmalte de la baldosa cerámica permite modificar las cantidades de sodio presentes en este en un amplio rango, lo cual ayuda a una mejor cristalización de la estructura kesterita [160].…”
