Mixing two Organic Dyes to Fabricate Solar Cell Concentrator

摘要

A luminescent solar concentrator (LSC) was made by mixing two organic dyes; erythrosine and, eosin y then silicon solar cell efficiency was measured before and after synthesizing the luminescent concentrators having the two mixing dyes. Significant improvement was noticed in the solar cell efficiency from (9.03) to (11.24). The best concentration of the mixing dyes was identified with equal proportions. Also, (Voc, Ish, FF, x) was calculated. The sun at the center of the solar system is a yellow small star, a ball flame of gasps. The solar system is held together by gravity of sun, holding all the small particles and the big planets of debris in the solar orbit. Electric currents in the sun generate a magnetic field that is carried out through the solar system by the solar wind a stream of electrically charged gas blowing outward from the sun in all directions. Solar cell (Photoelectric cell) is considered a device used to convert the light energy into electricity directly via photovoltaic, and not only with sunlight source; cells are considered photovoltaic even with lamplight, or any artificial light, etc. Hence, the solar cells operate in spot and are without movable parts to be exposed to defects; consequently, do not have to be repaired or provided with fuel, but they need cleaning from time to time due to pollution by smoke and dust, which causes them to be less efficient.
