Effect of hydrostatic pressure on the photocurrent density of $${\mathbf{InGaN/GaN}}$$ multiple quantum well solar cells

In this paper, a numerical model is used to analyze photovoltaic parameters according to the electronic properties of \({\text{InGaN/GaN}}\) multiple quantum-well solar cells (MQWSC) under hydrostatic pressure. Finite-difference methods are used to acquire energy eigenvalues, and their corresponding eigenfunctions of \({\text{InGaN/GaN}}\) MQWLED and the hole eigenstates are calculated via a \(6 \times 6\) k.p method under applied hydrostatic...
