“…From Fig. 4b, combined with the band gap, the CBM of FeS 2 NCs film is 3.9 eV, which agrees with the results got by cyclic voltammetry measurement43. So the VBM is 4.9 eV which is 1 eV higher than that due to narrower band gap in our case.…”

A seedless hydrothermal method is developed to grow high density and vertically aligned ZnO micro/nanowire arrays with low defect density on metal films under the saturated nutrition solution. In particular, the mechanism of seedless method is discussed here. A buffer layer can be confirmed by transmission electron microscopy (TEM), which may release the elastic strain between ZnO and substrate to achieve this highly mismatched heteroepitaxial structures. Based on ZnO micro/nanowire arrays with excellent wettability surface, we prepared ZnO-FeS2-CuI p-i-n photodiode by all-solution processed method with the high rectifying ratio of 197 at ±1 V. Under AM 1.5 condition, the Jsc of 0.5 mA/cm2, on-off current ratio of 371 and fast photoresponse at zero bias voltage were obtained. This good performance comes from excellent collection ability of photogenerated electrons and holes due to the increased depletion layer width for p-i-n structure. Finally, the high responsivity around 900 nm shows the potential as near infrared photodetectors applications.

“…The O 1 s spectrum in Fig. 3f also shows the SO 4 2- at 532 eV4243. Therefore, the pyrite FeS 2 is the dominant species, but the presence of SO 4 2- indicates the outside FeS 2 NCs convert to FeSO 4 partially after air exposure.…”

Transition metal sulfides (TMSs) are of special interest in energy conversion and storage devices. Amongst all sulfides, fool's gold or iron pyrite (FeS 2 ) is potentially an attractive candidate for photovoltaic applications. Iron pyrite has risen to prominence due to its distinct properties and abundance in nature to meet the large scale needs. It is considered as environmentally benign solar absorber material with high absorption coefficient, α > 6 x10 5 cm À 1 for λ � 700 nm and suitable energy bandgap (E g = 0.95 eV). Numerous physical and chemical methods have been employed to deposit nanocrystalline pyrite thin films directly from source materials or indirectly by sulfuration. This review gives an overview of pyrite as a low cost photovoltaic absorber material for contemporary solar cell structures. In addition, practical approaches like the rational design of nanocomposites, band gap engineering and nanostructure synthesis of pyrite for improving its properties particularly photovoltaic properties are also deliberated. Moreover, limitations, challenges, remedies and prospects of pyrite as potential photovoltaic material are also reviewed to further advance the development of pyrite-based solar cell configurations.[a] Dr.at a low precursor concentration, pyrite nanocubes (125-250 nm in 20-180 min) were obtained due to low nuclei concentration and slow growth (diffusion limited) in quasiequilibrium. The anisotropic structures nanodendrites were 2 3 4 5 6 7 8

“…The inverted ternary hybrid solar cells demonstrate air-stability aer aging 28 days exposed in air, with an actual improvement of V oc and FF that resulted in an average 28% increase in PCE. 184 Recently, a paper by Itskos et al 71 brought insights on how systematic photophysical investigation of binary mixtures can be used to understand the complex behavior of ternary mixtures. The authors prepared heterojunctions of a low band gap silicon-bridged dithiophene copolymer (Si-PCPDTBT) and oleic acid capped PbS QDs with diameters in the 2.9-9.2 nm range.…”

A comprehensive review of the application of chalcogenide nanoparticles in polymer solar cells

2014

View full text Add to dashboard Cite

In this review the use of solution-processed chalcogenide quantum dots (CdS, CdSe, PbS, etc.) in hybrid organic-inorganic solar cells is explored. Such devices are known as potential candidates for low-cost and efficient solar energy conversion, and compose the so-called third generation solar cells. The incorporation of oxides and metal nanoparticles has also been successfully achieved in this new class of photovoltaic devices; however, we choose to explore here chalcogenide quantum dots in light of their particularly attractive optical and electronic properties. We address herein a comprehensive review of the historical background and state-of-the-art comprising the incorporation of such nanoparticles in polymer matrices. Later strategies for surface chemistry manipulation, in situ synthesis of nanoparticles, use of continuous 3D nanoparticles network (aerogels) and ternary systems are also reviewed.
