InAs/GaAs Quantum Dot Solar Cell

In this work Silvaco TCAD have been used to model quantum dot solar cell. It was found that the addition of InAs QD(quantum dot) in the intrinsic layer of hetero-structure InGaP/GaAs p-i-n solar cell extends the absorption range of the solar cell, thereby giving rise to efficiency enhancement of the QD solar cell by 3.8851 % it was also observed that the fill factor increases from 83.2724% to 8...

Improving Si solar cell performance using Mn:ZnSe quantum dot-doped PLMA thin film

Poly(lauryl methacrylate) (PLMA) thin film doped with Mn:ZnSe quantum dots (QDs) was spin-deposited on the front surface of Si solar cell for enhancing the solar cell efficiency via photoluminescence (PL) conversion. Significant solar cell efficiency enhancements (approximately 5% to 10%) under all-solar-spectrum (AM0) condition were observed after QD-doped PLMA coatings. Furthermore, the real ...

Quantum Dot Solar Cells

Advanced concepts for high efficiency solar cells such as hot carrier effects, Multi-Exciton Generation (MEG), and Intermediate-Band (IB) absorption in low-dimensional nanostructures are under focused research topics in recent years. Among various potential approaches, this chapter is devoted to the device physics and development of the state-of-the-art technologies for quantum dot-based IB sol...

Efficiency Optimization in a Rainbow Quantum Dot Solar Cell

In this paper, we have calculated the efficiency and I-V characteristic of a Quantum Dot (QD) Solar Cell (SC) based on multi-stacked different-sized InGaN QDs on GaN substrate. In order to engineering the confinement states of QDs, we have inserted differentsized QDs in i-region of a p-i-n structure which includes different layers. This leads to Rainbow SCs.
