Inexpensive, Earth-Abundant, and Tunable Hole Transport Material for CdTe Solar Cells
Project ID: D2017-08Background Photovoltaic (PV) cells have been produced with a wide variety of materials for each functional layer. The typical PV is a substrate layer coated with a semiconductor layer and two ohmic contacts. Thin film solar cells use a thin absorbing layer, such as Cadmium telluride (CdTe). CdTe is the most eco-friendly, high e...
Iron Pyrite Nanocrystal Back Contact for CdTe Solar Cells
Project ID: D2014-32 Background Photovoltaic (PV) cells have been produced with a wide variety of materials for each functional layer. The typical PV is a substrate layer coated with a semiconductor layer and two ohmic contacts. Thin film solar cells use a thin absorbing layer, such as Cadmium telluride (CdTe). CdTe is the most eco-friendly, high ...
Filling Pin Holes, Weak Shunts, and Scribe Lines of Photovoltaic Devices
Project ID: D2008-08Background:During the fabrication of semiconductor devices, undesirable and detrimental holes or scribe lines are often created through the layers of the device. These structural defects often expose the transparent conductor layer and when the final metal layer is applied an electrical contact called a shunt is created betwee...
