Process


 

At the core of Xunlight Kunshan’s technology are the semiconductor compositions called thin-film silicon (tf-Si) which are used to convert sunlight into electricity. These materials are ideal solar energy technologies for many applications for the following reasons:

  • Efficient absorption of sunlight with ~1 μm thick film
  • Low manufacturing cost
  • Produced at low temperatures with short energy payback time
  • Can be used with low-cost substrates such as plastic, glass, and metal
  • Proven manufacturing process and product durability
  • More energy output per rated Watt
  • No toxic substance in the product
  • No supply shortage
  • Multi-junction device structure for higher conversion efficiency

Xunlight Kunshan utilizes an industry-leading roll-to-roll manufacturing process to produce solar cell layers. In just one integrated steps, this process transforms a strip of steel three feet wide and a mile long into the largest solar cell in the world. This giant solar cell is then cut, wired, interconnected and encapsulated into finished flexible thin-film silicon PV module products
