Efficiency Improvement Analysis for Recent High-Efficient Solar Cells

Abstract

The total 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, MultiJunction 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
