Abstract. Libya is one of the oil exporters and natural gas exporters to become one of the top lists of primary energy sources in the world. On the other hand, Libya, like other countries in the world suffers from high energy consumption, high conventional energy prices and environment issues, combined with rapid demand growth. As a result, the Renewable Energy Authority of Libya (REAOL) has been founded to promote the development of renewable energy in Libya to increase the utilization of renewable energy from 6% to 10% by the year of 2020. This study corresponds to a revision of the current scenario of energy resources; provide future potential of renewable energy resources in Libya and implementation of the future projects for the utilization of renewable energy. This study shows that there is huge potential for renewable energy in Libya, especially solar and wind. The Libyan government will have to be more aggressive targets to promotion of renewable energy to achieve environmental sustainability in Libya.

“…10 Mais tarde, na década de 1870, Willoughby Smith, W. G. Adams e R. E. Day observaram o efeito fotovoltaico usando selênio. 20 Esse fato possibilitou que, em 1883, Charles Fritts construísse a primeira bateria solar com folhas de selênio, com uma eficiência de apenas 1%, mas que gerou grande repercussão pelo fato de que naquela época não havia geração de energia sem a queima de combustíveis. 10 Foi então que, em 1954, surgiu a primeira célula solar à base de silício, com eficiência de 6%, desenvolvida por Chapin e colaboradores da Bell Labs.…”

Recebido em 31/01/2017; aceito em 7/8/2017; publicado na web em 02/10/2017 PEROVSKITES SOLAR CELLS: A NEW EMERGING TECHNOLOGY. Solar energy has been considered as an important source of clean and safe energy to overcome the problems associate to the burn of fossil fuels (e.g. climate changes, pollution, health problems, etc.). In the area of photovoltaics, devices that convert solar energy into electricity, perovskites solar cells (PSC) have attracted great attention due to their rapid development, high energy conversion efficiency, diversification of the processing methods and different materials. The fantastic properties of the hybrid perovskite materials, such as high absorption coefficient, direct and tunable bandgap, ambipolar charge carrier, simple preparation, etc., have quoted this technology as one the most important in this century. The rapid development of PSC has provided a significant increase in energy conversion efficiency, which was first reported, in 2009, as 3.8% and now reaches up to 22.10%, according to the National Laboratory of Renewable Energy (NREL). Many studies have been carried out to further increase the efficiency of devices and solve problems as the instability of the material, and the presence of lead, so that the PSC can be applied commercially. This paper presents a review on PSC and the major advances reported in device's architecture, preparation methods, novel materials and interface engineering.Keywords: solar cell; perovskites; perovskites solar cells. INTRODUÇÃOHá muitos anos a humanidade tem feito uso de combustíveis fósseis para satisfazer grande parte da demanda de energia. Porém, com a diminuição progressiva das reservas de combustíveis fósseis, deterioração do meio ambiente (devido ao efeito estufa), poluição do ar e água e, consequentemente, com os problemas de saúde humana associados ao aquecimento global, além das questões econômicas e políticas relacionadas à saúde e preservação do meio ambiente, o desenvolvimento de fontes alternativas de energia tem se tornado cada vez mais importante.1,2 Tendo em vista essas preocupações, a energia solar fotovoltaica pode ser considerada umas das fontes de energia alternativa mais promissora, pois provém de uma fonte abundante, limpa e segura, não gera ruídos e ainda permite a geração de energia elétrica em áreas remotas. 3A energia solar é, de uma forma ou de outra, a fonte de quase toda a energia na Terra.4 O sol fornece ao nosso planeta cerca de 10.000 vezes mais energia que o nosso consumo diário global. A energia solar pode ser convertida em calor, o qual pode ser utilizado diretamente para o abastecimento de água quente, ou em eletricidade, através do efeito fotovoltaico, nas células solares. 5,6 A constituição básica de uma célula solar é baseada em duas camadas de semicondutores (junção), sendo uma camada contendo carga positiva (p) e outra contendo carga negativa (n), que geram corrente elétrica quando expostas à radiação solar.7 Atualmente, as células solares são classificadas em três tipos, a saber: Células Solares de...

“…Similarly, this concept could be applied to c-Si solar cells as well. Particularly, low-cost dielectric materials with large bandgap (above 3 eV) have already been widely used in c-Si solar cells, such as silicon nitride (SiN x ), aluminum oxide (Al 2 O 3 ), and silicon dioxide (SiO 2 ) [15]. In addition, these dielectric materials have been reported to provide excellent surface passivation for c-Si solar cells [16,17].…”

Nanostructures have been widely used in solar cells due to their extraordinary photon management properties. However, due to poor pn junction quality and high surface recombination velocity, typical nanostructured solar cells are not efficient compared with the traditional commercial solar cells. Here, we demonstrate a new approach to design, simulate, and fabricate whole-wafer nanostructures on dielectric layer on thin c-Si for solar cell light trapping. The optical simulation results show that the periodic nanostructure arrays on dielectric materials could suppress the reflection loss over a wide spectral range. In addition, by applying the nanostructured dielectric layer on 40 μm thin c-Si, the reflection loss is suppressed to below 5% over a wide spectra and angular range. Moreover, a c-Si solar cell with 2.9 μm ultrathin absorber layer demonstrates 32% improvement in short circuit current and 44% relative improvement in energy conversion efficiency. Our results suggest that nanostructured dielectric layer has the potential to significantly improve solar cell performance and avoid typical problems of defects and surface recombination for nanostructured solar cells, thus providing a new pathway towards realizing high-efficiency and low-cost c-Si solar cells.
