High Radiation Resistance Inverted Metamorphic Solar Cell

Completed Technology Project

Project Description

High Radiation Resistance Inverted Metamorphic Solar Cell
The innovation in the proposed SBIR Phase I project is the development of a unique triple unction inverted metamorphic technology (IMM), which will enable the manufacture of very lightweight, low-cost InP-based multijunction solar cells. The proposed IMM technology will consist of an all indium and phosphorous-based structure, which is designed to improve the radiation resistance properties of the triple junction solar cell. Because of the intrinsic radiation hardness of InP materials, this material system is of great interest for building solar cells suitable for deployment in very demanding radiation environments such as medium earth orbit and missions to the outer planets. It is expected that an efficiency greater than 30% could be realized with this new IMM structure. More »
