The shingle technology was developed in the 1960s. First with the drastic fall in silicon solar cell costs and the successful realization of conductive glues, however, was the market readiness of the technology reached. Through shingling, the gaps between the cells disappear, maximizing the possible module area used for electricity production and giving the module a homogeneous, aesthetic appearance
According to Fraunhofer ISE news, Due to mechanical stresses, shingle cells cannot be soldered like conventional cells. Now with the adhesive technology, it has first become possible to manufacture reliable and robust shingle cell strings. The adhesive not only balances out the thermal expansion of the glass caused by varying ambient temperatures but also is lead-free. The cell stringer from the company teamtechnik Maschinen und Anlagen GmbH applies the electrically conductive adhesive, or ECA, using a screen-printing technique and connects the cells with high precision. Achim Kraft, head of team Interconnection Technologies at Fraunhofer ISE is positive: “The aesthetics and the high power density will push the shingle technology forward, especially in the automotive industry and for building-integrated applications. European module manufacturers inquire increasingly about application-oriented developments and technology assessments for shingle solar cells.” ——————–***——————–
