Application of InN based quantum dot in reducing short circuit current variation of solar cell above room temperature
(Trans Tech Publications, 2014-01)This paper focuses on the applicability of InN based quantum dot in the active layer of the solar cell to reduce the short circuit current variation above the room temperature. We have investigated numerically the effect ... -
A comparative study of confined carrier concentration of laser using quantum well and quantum dot in active layer
(Trans Tech Publications, 2013)This paper presents a comparative analysis of the characteristics of confined carrier concentration in the gain medium as well as the carrier concentration at the threshold. We have studied extensively these phenomena by ... -
Effect of lattice constant on band-gap energy and optimization and stabilization of high-temperature In xGa 1 -xN quantum-dot lasers
(Springer US, 2012-07)We analyze the effect of the lattice constant on the band-gap energy of In x Ga1−x N and optimize the structure of the device with a separate-confinement heterostructure. To vary the lattice constants, we change the In ... -
Improvement of absorption characteristics of solar cell above room temperature using quantum dot
(Engg Journals Publications, 2013-10)This paper presents a theoretical study on the light absorption characteristics of solar cell. We have analyzed the temperature dependence of the absorption coefficient of light and the percentage of the incident light ... -
Minimization of open circuit voltage fluctuation of quantum dot based solar cell using InN
(Trans Tech Publications, 2013)This paper reports the improvement of open circuit voltage stability of solar cell using InN based quantum dot in the active layer of the device structure. We have analyzed theoretically the temperature dependence of the ...
