“…In addition to semiconducting n-type materials, p-type semiconductors, mainly NiO, can also be used to fabricate mesporous scaffolds [114,115]. In this configuration, a compact layer and mesoporous scaffold based on NiO are subsequently deposited onto a FTO substrate, establishing a hole transport pathway.…”

The dawn of a new era in optoelectronic technologies has emerged with the recent development of the organic-inorganic hybrid halide perovskite. Its exceptional attributes, including high carrier mobility, an adjustable spectral absorption range, long diffusion lengths, and the simplicity and affordability of fabrication render it one of the most exceptional and market-competitive optoelectronic materials for applications in photovoltaics, light emitting diodes (LED), photodetectors, lasers, and more. Moreover, its versatility in device architecture and ability to achieve relatively high performance devices via various processing techniques makes perovskites a highly promising material for various practical applications. Here, we review the organic-inorganic hybrid halide perovskite and delve into its recent progress and relevant applications. Published by Elsevier Ltd.

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...

“…Tian et al [126] reported an efficiency of 0.16 % while Wang et al [127] were able to achieve up to 0.71% (0.91% at reduced light intensity). These first reports used MALH in a manner analogous to that reported in 2011 by the group of Nam-Gyu Park [128], and brought the material to the attention of the solar cell community.…”

Third generation photovoltaics are based on the concept of providing high conversion efficiencies with low device production costs. As such, second generation concepts, such as Dye-sensitized Solar Cells (DSCs), serve as a good starting point for the development of these new devices. Tandem DSC devices are one example of such a concept, and can be constructed using two photoactive electrodes (one photoanode and one photocathode) inside the one cavity, increasing the theoretical efficiency limit by around 50% as compared to the conventional design. As there has been substantial effort devoted to the development of ntype DSCs, the focus of researchers investigating tandem DSCs has been to create high performance p-type systems, which operate by an analogous, but inverted, mechanism to n-type DSCs.
