Solar Cell Device

Gold nano-island structures were fabricated on the light-illumination side of an organic solar cell device to investigate how the light scattering by localized surface plasmon resonance influences the quantum efficiency of an organic solar cell. A light beam from a solar simulator experiences multiple interaction processes with the gold nanostructures before reaching the organic active material, which may include the scattering, the reflection, and the absorption by the gold nano-islands. However, only the scattering process may partially contribute to the enhancement of the conversion efficiency. The reflection and absorption processes make the gold nanostructures act as “blockers” and prevent the light from reaching the solar cell device. Even the scattering process may not always play positive roles in improving the performance of the device. Thus, experimental studies in this work intend to find out a balance between the loss and the enhancement mechanisms, so that the efficiency of the solar cell can be improved. Our experimental results found a possibly optimized configuration of the gold nano-island structures, which leads to enhancement of the conversion efficiency of the solar cell device.

Abstract Double perovskite, Cs2AgBiBr6, is introduced as a lead-free perovskite solar cell. Device modeling of Cs2AgBiBr6 (DP) was accomplished to obtain the optimum parameters using the Solar Cell Capacitance Simulator (SCAPS). Two devices with two different hole transport layers (HTLs) were investigated, including P3HT and Cu2O. Please see manuscript .pdf for full abstract.

AbstractThe demands of ecofriendly technologies to produce a reliable supply of renewable energy on a large scale remains a challenge. A solar cell based on DSSC (Dye-Sensitized Solar Cell) technology is environmentally friendly and holds the promise of a high efficiency in converting sunlight into electricity. This manuscript describes the development of a light harvester system as a main part of a DSSC. Congo red dye has been functionalized with metals (Fe, Co, Ni), forming a series of complexes that serve as a novel light harvester on the solar cell. Metal-congo red complexes have been characterized by UV-VIS and FTIR spectroscopy, and elemental analyses. The performance of metal complexes in capturing photons from sunlight has been investigated in a solar cell device. The incorporation of metals to congo red successfully improved of the congo red efficiency as follows: Fe(II)-congo red, Co(II)-congo red and Ni(II)-congo red had efficiencies of 8.17%, 6.13% and 2.65%, respectively. This research also discusses the effect of metal ions on the ability of congo red to capture energy from sunlight.

Influence Of Temperature On

Semiconductor materials cadmium sulfide (CdS) and cadmium telluride (CdTe) are employed in the fabrication of thin film solar cells of relatively excessive power conversion efficiency and low producing price. Simulations of thin film CdS/CdTe solar cell were carried out using SCAPS-1D. The influence of temperature field on the variation of CdTe solar cell parameters such as current–voltage, capacitance–voltage characteristics and the external quantum efficiency was investigated theoretically. For use temperatures, one obtains the external quantum efficiency has the same profiles. However, the effect of the temperature on the Mott-Schottky curves is slightly noted by variations on the characteristics. This conclusion can be used by solar cell manufacturers to improve the solar cell parameters with the biggest possible gain in device performance.
