Paper Abstract

This paper reviews the work of several teams at ARL. In the first section a summary of the work done by the photovoltaic devices team is presented, the team is using quantum dots to enhance the efficiency of solar photovoltaic devices. We have discovered that doping the quantum dots is critical in enhancing the efficiency of the solar cells. In the quantum well arena we are developing type II SLS detector material for high performance focal plane array applications, so far we have observed that the minority carrier lifetimes have been short. This presents a major barrier towards the realization of high performance focal plane arrays. This paper discusses some of the details of type II SLS material studies as they pertain to minority carrier lifetime studies.
