Simulation of ideal material blocks using cellular automata
Correia Ramos, C.; El Bouziani, Nada; Tlemçani, Mouhaydine; Fernandes, SaraWe consider deterministic and probabilistic cellular automata to study and describe certain types of patterns in idealized material blocks. We have particular interest in patterns similar to fractures. The internal structure of these material blocks is assumed to be unknown and probabilistic cellular automata are used to obtain distributions for the referred internal structure. We consider the 1D case. Certain ...
Optimisation and Analysis of the Perovskite Solar Cell
Afonso, Daruez; Mesbahi, Oumaima; Bouich, Amal; Tlemçani, MouhaydineThe search for better conversion efficiency and the low production cost of solar cells has sparked the interest of several researchers with the aim to find new materials to meet the global challenges of the energy matrix [1, 2, 3]. This has made the inorganic halide, Cesium Lead Iodide (CsP bI3), one of the most promising due to its stability and, on the other hand, better efficiency compared to other perovskit...

Usage of non-invasive technique to diagnose a photovoltaic plant
Esposito, Marcelo; Calegari, Renato; Guerreiro Marques, Joaquim; Mesbahi, Oumaima; Tlemçani, MouhaydineThe present work utilizes an intelligent technique to lower photovoltaic systems’ operating and maintenance costs. In 2013, inverter manufacturer Huawei pioneered this concept with the development of multi-MPPT (Maximum Power Point Tracking) string inverters covering 14 different types of faults of photovoltaic systems. So far, the main advantage that the authors of this work have identified when using Huawei’s...
