Embodiment Construction

[0036] first reference figure 2 with image 3 , one embodiment of a photovoltaic (PV) module is indicated generally at 100 . figure 2 A perspective view of a PV module 100 is shown in . image 3 is like figure 2 A cross-sectional view of the PV module 100 taken along line A-A is shown in . The PV module 100 includes a laminate 102 and a frame 104 surrounding the laminate 102 .

[0037] Laminate 102 includes a top surface 106 (also referred to as the sun receiving side) and a bottom surface 108 ( image 3 shown in ). Edge 110 extends between top surface 106 and bottom surface 108 . In this embodiment, laminate 102 is rectangular. In other embodiments, laminate 102 may have any suitable shape. The laminate 102 has a width W 1 and length L 1 .

[0038] Such as image 3 As shown in , laminate 102 has a laminated structure including several layers 118 . Layer 118 may include, for example, a glass layer, an encapsulant, a non-reflective layer, an electrical connection l...

Abstract

A photovoltaic (PV) module includes a front layer, a rear layer, and a string of series connected PV cell segments laminated between the front layer and the rear layer. Each PV cell segment has a front surface including a front electrode and a rear surface including a rear electrode. Adjacent PV cell segments are overlapped by an overlap amount with the front electrode of one of the adjacent PV cell segments disposed under and in direct contact with the rear electrode the other of the adjacent PV cell segments. At least one adhesive strip is attached to the bottom surfaces of a pair of adjacent PV cell segments.

Description

[0001] Cross References to Related Applications [0002] This application claims US Provisional Patent Application Serial No. 62 / 272,950, filed December 30, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates generally to photovoltaic (PV) modules and, more particularly, to advanced interconnection systems and methods for producing strings of shingled PV cells for PV modules. Background technique [0004] Some known photovoltaic (PV) strings are constructed by shingling the cells using PV cell segments cut from full size PV cells. Constructing a PV module using shingled strings reduces electrical and optical losses compared to conventional solar modules that use copper tape on silver bus bars to solder full-size cells. FIG. 1 is a side view of a typical apparatus 10 for producing shingled battery strings. PV cell segment 20 is positioned above PV cell segment 30 . The PV cell segment 20 has a bac...
