Latest Patents
Migliorato holds a patent for "Heterojunction photovoltaic devices employing I-III-VI compounds." This patent describes photovoltaic devices constructed from a principal body of copper indium selenide (CuInSe.sub.2) with a hetero-epitaxial layer of a high bandgap semiconductor, such as an n-type layer of cadmium sulfide (CdS). The device can function as a photovoltaic detector for modulated radiation, achieving a response time as low as 5 nsec under a reverse bias of approximately two to three volts. When configured without a high-resistance intermediate region, the device serves as a solar cell, demonstrating absolute photovoltaic quantum efficiencies of up to 70 percent. The quantum efficiency of the solar cell type remains relatively flat between 0.55 and 1.25 µm. Additionally, with forward bias, the device operates as a light-emitting diode, exhibiting external electro-luminescent quantum efficiency of about 1×10^-4 at room temperature and about 1×10^-2 at 77°C, liquid nitrogen temperature.
