Shingled Cell Interconnection: A New Generation of Bifacial PV-Modules

Comparative Evaluation for Tracking the Capability of Solar Cell Malfunction Caused by Soil Debris between UAV Video versus Photo-Mosaic

“…Shingled solar modules are assembled with an imbricated structure on cells, which are interconnected directly similar to roof tiles. No visible busbars are another characteristic of shingled-type solar modules [28]. Chaichan and Kazem (2020) address that the illumination intensity on the solar cell is reduced according to the amount of deposited soil [29].…”

How to assess the electrical quality of solar cell interconnection in shingle solar modules

“…In photovoltaic community, such modules are called shingle solar modules and are known for their attractive appearance, their outstanding shading resilience, 3 and their unique potential for high module power densities. [4][5][6][7][8][9] The market share of shingle modules is expected to reach 10% within the next 7 to 10 years. 10 For an overview on the shingling technology, please refer to other works.…”

“…10 For an overview on the shingling technology, please refer to other works. [4][5][6][7][8][9]11,12 This work focuses on the electrical quality of shingle joints and omit all other aspects of the shingling technology such as the mechanical properties of shingle joints.…”

FoilMet®‐Interconnect: Busbarless, electrically conductive adhesive‐free, and solder‐free aluminum interconnection for modules with shingled solar cells

“…This, however, leads to higher consumption of precious resources as silver (Ag) or copper and magnifies shadowing effects. Another way to reduce the cell interconnection losses is the reduction of string currents by interconnecting separated, that is, smaller, solar cells such as half cells 2–10 and shingle cells 3,11–19 . Conventional shingling also increases the consumption of Ag 20 due to the necessity of Busbar and Ag containing electrically conductive adhesives (ECAs), however, reduces shadowing effects.…”

“…Another way to reduce the cell interconnection losses is the reduction of string currents by interconnecting separated, that is, smaller, solar cells such as half cells [2][3][4][5][6][7][8][9][10] and shingle cells. 3,[11][12][13][14][15][16][17][18][19] Conventional shingling also increases the consumption of Ag 20 due to the necessity of Busbar and Ag containing electrically conductive adhesives (ECAs), however, reduces shadowing effects. Since increased recombination occurs at postfiring separated edges, the cell pieces cannot be chosen arbitrarily small and a compromise between the reduction of series resistance and increase of edge recombination must be found.…”
