“…The company also believes that these cells can be manufactured using ink-based techniques including printing or casting (http://www.solarserver.com, 2012). In the lab scale, thin films of p-type CZTS have generally been used in conjunction with a layer of n-type semiconductors such as CdS to fabricate pn-junction solar cells (Tanaka et al, 2009). Recently, we have formed a pn-junction between a p-type CZTS layer and a fullerene derivative as the n-type material so that a solution-processed solar cell can be fabricated with materials based on earth-abundant and nontoxic elements that are more-importantly cadmium-free (Saha et al, 2012).…”

The progress of solar (photovoltaic) cells over the years is reported here. The selection and engineering of materials that have been used in the first to the fourth generation solar cells present salient features on why such newer materials were or would be introduced are discussed. Our perspectives to look beyond silicon as solar cell materials are presented. The issues of toxicity and earth-abundance of elements in forming active materials of solar cells are discussed. Measurement parameters, methods to improve performance, and mechanism of operation of different solar cells have also been discussed.

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

“…The natural and synthetic CZTS differ slightly in their lattice parameters. A broad range of techniques have been explored to deposit CZTS films: sulfurization of sputtered [3][4][5] or evaporated [6] stacked films, spray method [7,8], sol-gel method [9], hydrazine deposition [10], and electrode deposition [11]. Their properties have been extensively studied both experimentally [12][13][14][15][16][17][18][19] and theoretically [20][21][22][23].…”

The substitution of cation atoms by V, Cr and Ir in the natural and synthetic quaternary Cu2ZnSnS4 semiconductor is analyzed using first-principles methods. In most of the substitutions, the electronic structure of these modified CZTS is characterized for intermediate bands with different occupation and position within of the energy band gap. A study of the symmetry and composition of these intermediate bands is carried out for all substitutions.These bands permit additional photon absorption and emission channels depending on their occupation. The optical properties are obtained and analyzed. The absorption coefficients are split into contributions from the different absorption channels and from the inter-and intra-atomic components. The sub bandgap transitions are significant in many cases because the anion states contribute to the valence, conduction and intermediates bands. These properties could therefore be used for novel optoelectronic devices.
