The energy predicament, due to the impending Hubbert’s Peak Oil theory combined with the environmental consequences of CO2 emissions, dictate the need for a rapid transition from fossil fuels to renewable and sustainable energy sources to power the social and economic global metabolism. The last few years have witnessed an exponential growth of renewable power produced in major developed countries, mostly from wind farms and photovoltaic (PV) plants.
The growing demand of energy represents the main driving force of research in the field of new PV materials and new technological solutions, in order to confront two apparent problems: the rarefaction of the mineral resources and the need of developing an environmentally friendly and sustainable energy supply system.
The aim of this Special Issue consists of attracting worldwide researchers in participating to create a state-of-the-art summary of the recent increase in scientific and technological knowledge on new materials for thin film technology. This could include specific references to the synthetic routes for absorber powders and crystals, to the strategies for the realization of thin film devices, the characterization of the mineralogical, crystal chemical, structural, thermodynamic and physical properties of substrates and devices, and perspectives for the subject.
In this respect, special emphasis will be given to new data on consolidated materials for thin film technology, such as for example, cadmium telluride (CdTe), copper indium gallium sulfides and selenides, Cu(In,Ga)S2/Se2 (CIGS, CIGSe), new promising materials such as kesterites,Cu2ZnSnS4 or Cu2ZnSnSe4 (CZTS, CZTSe), as well as other emerging materials for thin film solar cell applications.

Title: Spray-On Thin Film PV Solar Cells: Advances, Potentials and Challenges

Abstract: The ability to fabricate photovoltaic (PV) solar cells in large scale and with a competitive price is an essential prerequisite for commercialization of this technology. All or several layers of the polymer, dye-sensitized, quantum dot, copper indium gallium selenide and other similar solar cells may be processed in a solution and transferred to the substrate by atomizing the solution and carrying the spray droplets to the substrate to leave behind a thin film after evaporation of the solvent. In contrast to high energy-low vacuum and therefore expensive processes such as the chemical vapor deposition, the spray coating is performed at the atmospheric pressure using low cost equipment with the roll-to-roll process capability, making it an attractive fabrication technique, provided that high performance and uniform layers can be made. In this paper, the feasibility, recent advances and challenges of using spray coating process to fabricate solution processed thin film PV solar cells is discussed.

Title: Spray-On PEDOT:PSS and P3HT:PCBM Thin Films for Polymer Solar Cells

Abstract: PEDOT:PSS electron-blocking layer, and PEDOT:PSS + P3HT:PCBM stacked layers are fabricated by ultrasonic atomization and characterized by scanning electron microscopy (SEM) and optical profilometry. The measured thicknesses based on SEM and optical profilometry are quite different indicating the incapability of measurement techniques for non-uniform thin films. The thickness measurements are compared against theoretical estimations and a qualitative agreement is observed. Results indicate that the using a multiple pass fabrication strategy results in a more uniform thin film. It was also found that the film characteristics are strong function of solution concentration and spraying passes, and a weak function of substrate speed. Film thickness increases with solution concentration but despite the prediction of theory, the increase is not linear, indicating a change in the film porosity and density, which can affect physical and opto-electrical properties. Overall, while spray coating is a viable fabrication process for a wide range of solar cells, film characteristics can be easily altered by a change in process parameters.
