Stability Analysis of Solar Cell Characteristics Above Room Temperature Using Indium Nitride Based Quantum Dot

Abstract

This study represents the improvement of stability of solar cell characteristics above room temperature. We have analyzed theoretically the temperature dependence of three major characteristics of solar cell using Ge and InN based quantum dot in the active layer of the device structure. Among the major characteristics of solar cell we have investigated the rate of change of open circuit voltage, short circuit current and the output power of solar cell with respect to temperature. Numerical results obtained are compared. The comparison results reveal that the rate of change of open circuit voltage, short circuit current and output power have been reduced significantly using InN based quantum dot in the active layer of the solar cell. Hence the improvement in stability of these characteristics above room temperature has been achieved by using InN based quantum dot in the active layer of the solar cell.

A Comparative Analysis of Effect of Temperature on Band-Gap Energy of Gallium Nitride and Its Stability Beyond Room Temperature Using Bose–einstein Model and Varshni’s Model

“…Furthermore Group-III nitride semiconductor materials have been identified as a group of materials having greater potential than other groups of existing semiconductor materials. Therefore, these materials are widely used to fabricate optoelectronic semiconductor devices in the range between visible short-wavelength to the ultraviolet region [6,7]. Hence, a detailed numerical analysis on the temperature dependence from low to high temperature of bandgap energy of these materials is necessary for a promising design of such devices especially for high temperature applications.…”

EFFECT OF AMBIENT AIR CONDITIONS ON LOW FREQUENCY NEGATIVE CAPACITANCE OF NC-TIO₂/P3HT HETEROJUNCTION SOLAR CELLS

“…The interface and bulk region of solar cells extend only few hundred nanometer and their properties affect on the devices performance and stability (Jørgensen et al, 2008;Rahid et al, 2013). Thus, organic materials have been under intensive investigation to improve the properties of interface and bulk region.…”
