Here, the effect of lightly Niobium doped TiO2 layer on the performance of perovskite solar cells has been studied by using solar cell capacitance simulator (SCAPS). N addition, the effects of Niobium concentration, buffer film thickness and operating temperature on the performance of the perovskite solar cell are investigated. For doping level of 3.0 mol% into the TiO2 layer, cell efficiency o...

One major problem of the conventional solar cells is low conversion efficiency. In this work, we have proposed a new design including hemisphere texturing on top and metallic plasmonic nanostructure under the silicon layer to enhance the optical absorption inside the photosensitive layer.    The finite-difference time-domain (FDTD) method has been used to investigate the interaction of light wi...

today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. one of the almost endless and pure energy which have been paid attention over the years is the solar energy. solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. significant improvement has been made...

Numerical modeling of polycrystalline thin-film solar cell serves as an imperative procedure to test the suitability of proposed physical clarification and to anticipate the effect of physical changes on cell performance. All in all, this must be conducted with only partial knowledge of input parameters. In this paper, we evaluated the numerical simulation of CdS/CIGS tandem multi junction sola...

nanocrystalline titanium (iv) oxide paste has been deposited on fluorine doped tin oxide glass substrate by the blade method. the deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. the electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. avaspec 2.1 spectrophotometer was used to obtain the ...

today, using new and renewable energy sources to replace fossil fuels is greatly expanded. the solar cells are devices that convert solar energy to electrical energy. solar cells based on organic materials, especially proteins, are one of these solar cells. for example, bacteriorhodopsin (br) which is one of the membrane proteins in halobacterium salinarum could be used in solar cells and parti...

We present temperature-dependent measurements and modeling for a thickness series of hydrogenated amorphous silicon nip solar cells. The comparison indicates that the maximum power density PMAX from the as-deposited cells has achieved the hole-mobility limit established by valence bandtail trapping, and PMAX is thus not significantly limited by intrinsic-layer dangling bonds or by the doped lay...

The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV ...
