Cuckoo Search Inspired Hybridization of the Nelder-Mead Simplex Algorithm Applied to Optimization of Photovoltaic Cells
Raka Jovanovic, Sabre Kais, Fahhad H. Alharbi
A new hybridization of the Cuckoo Search (CS) is developed and applied to optimize multi-cell solar systems; namely multi-junction and split spectrum cells. The new approach consis…
Convergent sum of gradient expansion of the kinetic-energy density functional up to the sixth order term using Pade approximant
A. Sergeev, R. Jovanovic, S. Kais +1
The gradient expansion of the kinetic energy functional, when applied for atoms or finite systems, usually grossly overestimates the energy in the fourth order and generally diverg…
Delocalized Quantum States Enhance Photocell Efficiency
Yiteng Zhang, Sangchul Oh, Fahhad H. Alharbi +2
The high quantum efficiency of photosynthetic complexes has inspired researchers to explore new routes to utilize this process for photovoltaic devices. Quantum coherence has been…
Revealing the role of organic cations in hybrid halide perovskites CH3NH3PbI3
Carlo Motta, Fedwa El Mellouhi, Sabre Kais +3
The hybrid halide perovskite CHNHPbI has enabled solar cells to reach an efficiency of about 18\%, demonstrating a pace for improvements with no precedents in the…
Theoretical Limits of Photovoltaics Efficiency and Possible Improvements by Intuitive Approaches Learned from Photosynthesis and Quantum Coherence
Fahhad H Alharbi, Sabre Kais
In this review, we present and discussed the main trends in photovoltaics with emphasize on the conversion efficiency limits. The theoretical limits of various photovoltaics device…
Efficient method for localized functions using domain transformation and Fourier sine series
Raka Jovanovic, Sabre Kais, Fahhad H. Alharbi
An efficient approach to handle localized states by using spectral methods (SM) in one and three dimensions is presented. The method consists of transformation of the infinite doma…
