Sentence examples for sun spectrum from inspiring English sources

where α is the spectral absorption coefficient calculated from the transmittance spectra and I is the considered Sun spectrum.

However, most of the UC materials have some bottleneck problems associated with them, such as own only narrower excitation band matching with the sun spectrum, lower UC luminescence efficiency, and considerable heat losses.

Currently, the highest efficiency solar cells are GaAs-based tandem solar cells (GaAs, GaInP and Ge) achieving efficiencies greater than 32% (AM 1.5 G at one sun spectrum) [1].

Using the technique of thermoelectric generators, to convert the infrared part of the sun spectrum into electrical energy, we could increase the overall performance of a combined PV and TE solar cell by approximately 10%% of the PV, thereby achieving around 20%% efficiency with the combined system rather than the 17 18 % efficiency from the PV-only setup.

Aerosol optical depth (AOD) provides a useful characterization of the total absorption and scattering effect of particles in direct or scattered sunlight, and can be derived from sun spectra measured directly by sun photometers.

Scientists at the University of Cambridge in the UK have found a way to improve the efficiency of photovoltaic cells by as much as 25% through harnessing more of the sun's spectrum than most traditional silicon-based solar cells can.

AlGaAs single junction cells, designed to be bonded on a silicon cell for low concentrator photovoltaics (LCPV), were also manufactured reaching an efficiency of 15.9% under one sun AM1.5G spectrum for a 2cm2 cell.

Combining an earlier simulation report [30, 34] and total current density (J tot) value of 43.77 mA/cm2 which is obtained by integrating the sun's spectrum from 300 to 1100 nm, we mapped the loss percentage of total current density percentage (P loss) using different colors (as shown in Fig. 2a).

To harvest electricity over a wide range of the sun light spectrum, the multijunction design of stacked p n interfaces tuned to different bandwidths has been proposed.

To our knowledge, solar cells based on CuO and Cu4O3 have not achieved noticeable photovoltaic performance and have been less studied despite their bandgap being more appropriate for the sun's spectrum.

Therefore, the implementation of all-graphene photovoltaics, that is, a device in which both the active area and electrodes are made of graphene materials, could be able to harvest energy over the whole sun light spectrum, while offering unique properties such as ultralight weight (i.e., graphene is just one atom thick), mechanical flexibility, and optical transparency.
