Tin in PV

Tin was early in the race for new ‘earth abundant’ materials to replace expensive and rare elements used in current PV technologies such as gallium. The first generation product was a ‘kesterite’ copper tin zinc sulphide (CZTS) developed by IBM. More recently tin has gained attention in ‘lead-free’ products that have dramatically competitive performance, targeted at new markets for example on architectural glass. Tin is also being explored as a heat energy storage medium on farms that concentrate sunlight using mirrors. Apart from the materials themselves, this sector is already benefitting tin use in China particularly through increased use of solder ribbon used to join solar cells, and increased associated electronics production.
