Out of the nitride family, Indium Gallium Nitride alloy possesses a direct and wide energy band gap ranging from 0.7 eV for Indium Nitride up to 3.4 eV for Gallium Nitride, because of which it covers most of the solar spectrum thus serving as a wide band gap top cell in a mechanically stacked or a bounded multi-junction hybrid solar cell.

Since the open-circuit voltage V OC of the series multi-junction cell is the sum of the open-circuit voltages V OCs of the sub-cells, the cell temperature correlation coefficient dV OC /dT is also the sum of the temperature correlation coefficients of the sub-cells.

Indium gallium nitride (InGaN) is becoming a promising semiconductor material for fabrication of solar cells due to its high absorption coefficient (about 10 5 cm −1) and tunable (by its In content) direct band-gap, from 0.71 eV (E InN) to 3.43 eV (E GaN).Solar cells based on structures with variable In content should show a reduction of thermalization losses, absorbing
Two layers of indium gallium nitride, one tuned to a band gap of 1.7 eV and the other to 1.1 eV, could attain the theoretical 50 percent maximum efficiency for a two-layer multijunction cell. (Currently, no materials with these band gaps can be grown together.) Or a great many layers with only small differences in their band gaps could be stacked to approach the maximum
The advantage of indium gallium nitride, the first material the Berkeley Lab researchers proposed for a full-spectrum solar cell, is that the crystal lattice of all the different layers is the same. Because the material is inherently radiation hard, research continues on InGaN for satellite applications, although it has proved difficult to make a practical p-type
