Factors Affecting Quantum Solar Dots Efficiency

Saivya Singh | Pathways School Noida |


Abstract

Quantum dots are semiconductors that have a radius in nanometers. Because of their unique properties, they can be used in many industries like solar cells, biological imaging, and display technologies. This paper explains key factors that affect the efficiency of a quantum dot like size, surface passivation, charge carrier mobility, and absorption of light. These factors affect the efficiency of a quantum solar dot based on internal and external factors. In terms of the external factors, the focus area is the number of photons that can be absorbed by the quantum dot and how well these photons can be used to produce “excitons” which consist of an electron and its positively charged “hole” the greater the number of these excitons the more current would be produced in the quantum dot. Talking about the internal factors, the efficiency of the quantum dot depends on the internal architecture and how well can the charge be transported throughout the quantum dot to generate electricity.
