“…Under concentrated light, in all cases, the introduction of Si-ncs in the PEDOT:PSS layer (dotted lines in both figure 3 and figure 5) is beneficial to the overall performance of the solar cell. Since under concentrated light Si-ncs clearly show nonlinear PL properties [30], it is reasonable and highly likely that the device improvements originate from the down-conversion of high energy photons into red-photons [11,31]. The nanocomposite also slightly improves the V OC to 0.78 V in both organic and hybrid devices and the efficiency non-linear behavior of organic devices (Figure 3b) due to the Si-ncs/PEDOT:PSS layer is again observed for hybrid solar cells (Figure 5b).…”

Silicon nanocrystal (Si-nc) down-conversion is demonstrated to enhance organic and hybrid organic/inorganic bulk heterojunction solar cells based on PTB7:[70]PCBM bulk heterojunction devices. Surfactant free surface-engineered Si-ncs can be integrated into the device architecture to be optically active and provide a means of effective down-conversion of blue photons (high energy photons below ∼450 nm) into red photons (above ∼680 nm) leading to 24% enhancement of the photocurrent under concentrated sunlight. We also demonstrate that the down-conversion effect under 1-sun is enhanced in the case of hybrid solar cells where engineered Si-ncs are also included in the active layer.

“…The AR effect contributes dominantly, which could be attributed to the modification of refractive index gradient [19]. Since many other efficient AR approaches have been developed [19-22], the effect of AR will not be further discussed here.…”

Poly(lauryl methacrylate) (PLMA) thin film doped with Mn:ZnSe quantum dots (QDs) was spin-deposited on the front surface of Si solar cell for enhancing the solar cell efficiency via photoluminescence (PL) conversion. Significant solar cell efficiency enhancements (approximately 5% to 10%) under all-solar-spectrum (AM0) condition were observed after QD-doped PLMA coatings. Furthermore, the real contribution of the PL conversion was precisely assessed by investigating the photovoltaic responses of the QD-doped PLMA to monochromatic and AM0 light sources as functions of QD concentration, combined with reflectance and external quantum efficiency measurements. At a QD concentration of 1.6 mg/ml for example, among the efficiency enhancement of 5.96%, about 1.04% was due to the PL conversion, and the rest came from antireflection. Our work indicates that for the practical use of PL conversion in solar cell performance improvement, cautions are to be taken, as the achieved efficiency enhancement might not be wholly due to the PL conversion.

In this article is considered the data of species composition of pathogens of skin and visceral leishmaniasis in the South of Kazakhstan. The research results are shown that the studies within the stationary conditions landscapes differ by all indications, determining the intensity of epizootic: contamination of great gerbils, the nature of mosquito species complexes and their abundance on promastigots infected mosquitoes.Considering the above, there is basis to assume existence on the studied by us territory of the independent natural centers or well shown morphological shares of the natural centers of zoonotic skin leishmaniasis which, most likely are dated for the certain studied landscape.
