A method of preparing a resin infused random fiber mat including the step of forming a liquid dispersion mat of polymeric resin and fiber on a porous substrate.

Manufacture of composite dispersion based resin-infused random fiber mat

A solar module () comprising: (a) a plurality of interconnected photovoltaic cells (); (b) a forward protective layer (); (c) a rearward protective layer (); and (d) an reinforcement (); wherein the reinforcement is integrally located within the solar module and extends from a location substantially proximate to the forward protective layer to a location substantially proximate to the rearward protective layer.

Reinforcement PV laminate

The present invention uses a treatment that involves an etching treatment that forms a pnictogen-rich region on the surface of a pnictide semiconductor film The region is very thin in many modes of practice, often being on the order of only 2 to 3 nm thick in many embodiments. Previous investigators have left the region in place without appreciating the fact of its presence and/or that its presence, if known, can compromise electronic performance of resultant devices. The present invention appreciates that the formation and removal of the region advantageously renders the pnictide film surface highly smooth with reduced electronic defects. The surface is well-prepared for further device fabrication.

Method of making photovoltaic devices incorporating improved pnictide semiconductor films

The present invention provides strategies for providing photovoltaic devices that are more resistant to moisture and/or oxygen degradation and the accompanying migration of key elements such as Na, Li, and the lanthanoid series of elements from the absorber layer and that have enhanced service life and improved performance. These strategies are particularly useful in the fabrication of chalcogenide-based photovoltaic devices such as chalcogenide-based solar cells. These strategies incorporate a barrier region between the photovoltaic absorber region and the front side collection grid. The barrier region keeps moisture and/or oxygen from the absorber layer and contains key elements such as Na, Li, and Ln in the absorber layer. As a result, the absorber layer retains its performance capabilities for an extended period of time.
