Fabrication of coaxial TiO2/Sb2S3 nanowire hybrids for efficient nanostructured organic- inorganic thin film photovoltaics
(Royal Soc Chemistry, 2012-01-01)
We report on low-cost, all solution fabrication of efficient air-stable nanostructured thin film photovoltaics comprised of n-type Sb2S3 chemically deposited onto TiO2 nanowire array films, forming coaxial Sb2S3/TiO2 ...
Estimation of energy efficiency in solar photovoltaic panels considering environmental variables
(2018-10-25)
The present work has been made to find out the relationship between the efficiency of
two types of photovoltaics panels, monocrystalline and polycrystalline, and the weather variation
in the city of Bogota-Colombia. The ...
Estudo da eficiência energética na utilização de um sistema de resfriamento em painéis fotovoltaicos
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilProcessamento de Energias RenováveisUTFPR, 2017-03-13)
The solar and wind energy are potential solutions among clean energy sources. One of the biggest difficulties in the use of photovoltaic panels is the low efficiency in the solar conversion. This energy decrease during the ...
Dynamic modeling of a compressed air energy storage system in a grid connected photovoltaic plant
(Universidade Federal de Minas GeraisUFMG, 2016-04-18)
The main problem of renewable energy power plants is the intermittency of the source of energy. Therefore, instantaneous variations of power demand could not be properly recovered. For overcoming this problem, the best ...

(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2017-11-29)
This work presents a study of photovoltaic systems connected to single-phase power grid, which involves three topologies of DC-DC step-up converters, being the Classic Boost converter, the Quadratic Boost converter and the ...
Estudo de viabilidade para proposição de uma cooperativa solar fotovoltaica para Serra Nordeste do Rio Grande do Sul
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2017-07-28)
The generation of electricity from renewable sources is an energy efficiency solution to meet
the growing demand for energy in a sustainable way and to diversify the Brazilian energy
matrix. Within this context photovoltaic ...
Análise das equações de eficiência de inversores fotovoltaicos através de comparativos teóricos e práticos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEspecialização em Energias RenováveisUTFPR, 2017-07-05)
Photovoltaic Energy is being considerated a fundamental element when it comes to sustainable and clean energy. Developed countries already have solar energy as a considerable part of their energy mix. On the other hand, ...
Efficiency enhancement in solar cells using photon down-conversion in Tb/Yb-doped tellurite glass
(2016-12-01)
Management of the solar spectrum incident on a solar cell was studied using tellurite glasses doped with Tb3+ and Yb3+ ions as a cover slip. From the transmittance measurements through the doped glass, a red-shift of the ...
