Included activities starts

The activity starts with the production and import of "Film photovoltaic laminate" in this region.

Included activities ends

The activity ends with providing the "Film photovoltaic laminate" to the consumers of this product. Transportation is included; however, product losses during transport are negligible and therefore not included.

Description

This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.

Activity Description

The manufacturing process of copper indium gallium selenide (CIGS) thin-film photovoltaic modules includes the following steps: loading molybdenum-coated substrates, laser marking, substrate cleaning, metal precursor layer deposition, selenium vapor deposition, in-line selenization treatment, back surface cleaning, buffer layer deposition, front electrode deposition, front electrode inspection, busbar laying pretreatment, busbar welding, lamination, and junction box installation. The manufacturing process of amorphous silicon-germanium triple-junction thin-film photovoltaic modules includes the following steps: conductive glass edge grinding, cleaning, laser treatment, deposition, cooling, magnetron sputtering, annealing, ultrasonic welding, layer pressing, junction box installation, and testing. The manufacturing process of cadmium telluride (CdTe) thin-film photovoltaic modules includes substrate pretreatment, CCS deposition, and PN junction formation. sparking, etching treatment, back electrode preparation, encapsulation, product testing, and other processes.

Process Description

Thin-film photovoltaic modules are manufactured by depositing photovoltaic materials onto substrates such as glass, plastic, or metal. This unit represents a 1 Wp thin-film photovoltaic module, which is a weighted average of cadmium telluride, copper indium gallium selenide, and amorphous silicon-germanium triple-junction thin-film photovoltaic modules.
