SBIR/STTR
Highly Efficient InGaN-Based Solar Cells for High Intensity and High Temperature Operation, Phase I
Project Introduction
In this SBIR Phase I program, we propose to fabricate high-efficiency and radiation hard solar cells based on InGaN material system that can cover the whole solar spectrum by adjusting the alloy composition. The main program objectives include the fabrication of InGaN-based solar cells on large diameter substrates, with external efficiency in excess of 35%, and capable of long life operation in high radiation environment of space at elevated temperatures.

Anticipated Benefits
Potential NASA Commercial Applications: In addition to NASA applications, the development of high efficiency solar cells also appeals to the civilian/terrestrial sector. The use of more efficient solar cells, with capability to operate at higher temperatures, makes its possible to increase the power of an array with no increase in size or weight or to produce a lighter/smaller array with the same power. Improved efficiency means a reduction in launch and continuous operational costs for NASA and other government agencies involved in space-based operations.
