In order to improve the efficiency of these devices, the factors limiting their efficiency and stability must be investigated in detail. Due to the complexity of a MQW structure, compared with a simple pn junction, modeling the spectral response of these solar cells is not straightforward, and ad hoc methodologies must be implemented.
InGaN-based multi-quantum well (MQW) solar cells are promising devices for photovoltaics (e.g., for tandem solar cells and concentrator systems), space applications, and wireless power transfer. In order to improve the efficiency of these devices, the factors limiting their efficiency and stability must be investigated in detail.
The photoelectric conversion efficiency of InGaN/GaN multiple quantum well (MQW) solar cells has been investigated at high temperatures and the study revealed that their average value decreased from about 2.58% at room temperature to about 2.39% at a temperature of 500 °C.
Note: This paper is part of the Special Topic on Wide Bandgap Semiconductor Materials and Devices. InGaN-based multi-quantum well (MQW) solar cells are promising devices for photovoltaics (e.g., for tandem solar cells and concentrator systems), space applications, and wireless power transfer.
