Embodiment Construction

[0012] Reference figure 1 , An article 100 having two solar active elements is described. Each solar active element includes a rigid plate 104 and a photovoltaic (PV) cell 106 located in the frame of the rigid plate 104 and on the opposite side of the rigid plate 104 from the light incident side. The rigid plate 104 is at least partially transparent, including being transparent to photons in the frequency range associated with the PV cell 106. The frequency range associated with the PV cell 106 may include, but is not limited to, all or any part of the visible spectrum, infrared light, and / or ultraviolet light. In certain embodiments, the rigid sheet 104 may be provided in more than one layer and / or as a laminate. The rigid sheet material 104 may include protective coatings or layers, anti-reflective coatings, lensing, or other features known in the art. Exemplary and non-limiting materials for the rigid sheet 104 include glass, polymers, oxides and / or ceramics, polymer-oxid...

Abstract

An article of manufacture includes at least two solar active elements separated by a gap, with a flexible material provided to define the gap. The article provides for enhanced resilience and conformity to an installation surface.

Description

Invention field [0001] The present invention relates to improved photovoltaic devices, and more particularly, but not exclusively, to photovoltaic devices with enhanced conformity and resilience. Background technique [0002] Currently known high-efficiency photovoltaic (PV) devices use rigid photovoltaic cells and include rigid transparent plates. The photovoltaic cell cannot withstand high deformation, and the rigid transparent sheet is provided with a thickness sufficient to support the rigidity required by the device. This reduces the flexibility of the overall PV device, and provides reduced suitability, for example, suitability for top irregularities of devices used as roof panels. The thickness of the transparent sheet also increases the weight of the photovoltaic device. Some PV devices are sized to replace some building units, such as roof panels, and therefore result in large smooth surfaces, such as glass surfaces. The resulting surface can cause slippage problems. ...
