Solar Energy is highly competitive, not only between Renewable Energy but also compared with traditional fossil fuels. This fact is supported by studies in developed countries in Europe. This experience should take advantage of the developing countries, which may also have additional comparative advantages by supporting solar radiation throughout the year. This is the case of Africa. Besides, other...
Mixed bromide-iodide methylammonium lead-halide perovskites have been synthetized from methylamine, lead nitrate and the corresponding hydroX acid (X= I, Br) precursors and thereafter deposited as thin films onto FTO substrates by spin coating or dipping. Thin film perovskites were then characterized by X-Ray Diffraction, optical spectrometry and photoluminescence. All synthetized MAPbI3, MAPbBr3...
Perovskites have proved to be a promising candidate for solar cells. In this paper we present the simulations work related to the new topics; influence of temperature and multi-Sun (solar concentrator) on performance of perovskite based solar cells. The study shows the dependence of all PV parameters on the operating temperature and solar irradiance. Performance of the perovskite based PV devices...
Numerical modelling of photovoltaic solar cells is an important strategy to test the viability of proposed physical structures and their performance. This article introduces the concept of numerical simulation and explain the relevant physical models for the inside physical phenomenon like generation, recombination and transport of charge carriers (holes and electrons) in photovoltaic materials. This...
Solar cells based on II–VI semiconductors are among the leading candidates for low-cost photovoltaic conversion of solar energy due to their high absorption coefficients and therefore the low material consumption for their production. To understand the basics of photovoltaic (PV) cells, several types of simulation software are available. This work reports on the analysis of Zinc Telluride (ZnTe) thin...
One key factor for effective dissemination of renewable energies is the price of production. Energy production price depends on the maturity of related technology and also on economic factors, which are mainly related to incentive policies. This paper analyzes the energy production of a standard 10 kW photovoltaic plant connected to the grid and its economic profitability in terms of economic returns...
