Abstract:

The design and practical viability of an intermediate band solar cell incorporating low dimensional structures made with dilute nitrogen alloys of III-V semiconductors is investigated theoretically and experimentally. Modeling of optical and electronic properties of the proposed materials and device is undertaken. The study suggests potential for this new class of single junction devices to yield efficiencies and radiation tolerance comparable or exceeding those of existing multi-junction devices.
