Solar Cell Technology

The entire electricity demand of the whole earth, can be theoretically satisfied by harnessing the unlimited photon energy of the alpha source, the sun. Absorbing the solar power in a full efficient way is still on progress, due to the limitation of our solar cell technology. On commercial aspects, it is also promising but not up to the mark. Recent high efficient solar cell still leaves more space to improve the cell efficiency. On these circumstances, the use of Graphene, Multi-Junction Cells and Quantum Dot Cells will be helpful to increase the rate of recent research flow. This paper visualizes GaAs, InP, CdTe and Graphene implementations on four proposed basic models, which have showed a positive impact to overcome the losses and SQ limits. These models also postulate the maximization of the solar cell efficiency, omitting the corresponding losses along with maintaining the inter-junction relation suitably.

Experimental and theoretical study Porphyrin-grafted ZnO nanowire arrays were investigated for organic/inorganic hybrid solar cell applications. Two types of porphyrin – Tetra (4-carboxyphenyle) TCPP and meso-Tetraphenylporphine (Zinc-TPP)were used to modify the nanowire surfaces. The vertically aligned nanowires with porphyrin modifications were embedded in graphene-enriched poly (3-hexylthiophene) [G-P3HT] for p-n junction nanowire solar cells. Surface grafting of ZnO nanowires was found to improve the solar cell efficiency. There are different effect for the two types of porphyrin as results of Zn existing. Annealing effects on the solar cell performance were investigated by heating the devices up to 225 °C in air. It was found that the cell performance was significantly degraded after annealing. The degradation was attributed to the polymer structural change at high temperature as evidenced by electrochemical impedance spectroscopy measurements.
