US Classification:

136246, 438 73, 257E3111

Abstract:

A solar module includes a substrate, a plurality of electrically interconnected solar cells, and an upper separation gap. The solar cells are provided above the substrate. At least one of the solar cells includes a reflective electrode, a silicon layer stack and a light transmissive electrode. The reflective electrode is provided above the substrate. The silicon layer stack includes an n-doped layer provided above the reflective electrode, an intrinsic layer provided above the n-doped layer and a p-doped layer provided above the intrinsic layer. The light transmissive electrode is provided above the silicon layer stack. The upper separation gap is provided between the cells. The upper separation gap electrically separates the light transmissive electrodes in the solar cells from one another such that the light transmissive electrode of one of the solar cells is electrically connected to the reflective electrode of another one of the solar cells.

Assignee:

THINSILICION CORPORATION - Mountain View CA

International Classification:

H01L 31/00

US Classification:

136258, 136261

Abstract:

A photovoltaic cell includes a substrate, a semiconductor layer stack, a reflective and conductive electrode layer, and a textured template layer. The semiconductor layer stack is disposed above the substrate. The electrode layer is located between the substrate and the semiconductor layer stack. The template layer is between the substrate and the electrode layer. The template layer includes an undulating upper surface that imparts a predetermined shape to the electrode layer. The electrode layer reflects light back into the semiconductor layer stack based on the predetermined shape of the electrode layer.

US Classification:

136249, 438 59, 257E31043, 257E31047

Abstract:

A monolithically-integrated photovoltaic module is provided. The module includes an insulating substrate and a lower electrode above the substrate. The method also includes a lower stack of microcrystalline silicon layers above the lower electrode, an upper stack of amorphous silicon layers above the lower stack, and an upper electrode above the upper stack. The upper and lower stacks of silicon layers have different energy band gaps. The module also includes a built-in bypass diode vertically extending in the upper and lower stacks of silicon layers from the lower electrode to the upper electrode. The built-in bypass diode includes portions of the lower and upper stacks that have a greater crystalline portion than a remainder of the lower and upper stacks.

Abstract:

Layers of conductive foil and insulating material are configured to interconnect an array of rear-contact solar cells. An embodiment provides that the layer of conductive foil may be patterned to form repeating sets of electrically isolated, interdigitated fingers. Each set of interdigitated fingers may be used to connect the positive polarity contacts of a first rear-contact solar cell to the negative polarity contacts of a second, adjacent rear-contact cell. The insulating layer is attached to the patterned conductive foil and provides mechanical support and/or electrical isolation. In some embodiments, a protective backsheet may be disposed beneath the conductive foil and/or insulating layer to provide further mechanical support and environmental protection. In some embodiments, the layers of conductive foil and insulating material may be incorporated as an interconnect circuit in a rear-contact PV module.
