Abstract EN
It is well known that nitride-based devices suffer the polarization effects.
A promising way to overcome the polarization effects is growth in a direction perpendicular to the c-axis (nonpolar direction).
Nonpolar devices do not suffer polarization charge, and then they have a chance to achieve the high solar efficiency.
The understanding of the solar performance of non-polar InGaN-based solar cells will be interesting.
For a pin non-polar solar cell with GaN p- and n-cladding layers, the conduction band offset (or barrier height, ΔE) between an intrinsic layer and n-GaN layer is an important issue correlating to the efficiency and fill factor.
The efficiency and fill factor will be seriously degraded due to sufficiently high barrier height.
To reduce a high barrier height, some graded layers with an energy bandgap between the energy bandgap of n-GaN and InxGa1−xN intrinsic layer can be inserted to the interface of n-GaN and InxGa1-xN layers.
From simulation, it indicates that the insertion of graded layer is an effective method to lower energy barrier when there exists a high energy band offset in non-polar nitride devices.
