  • Method of curing solar cells to reduce lamination induced efficiency loss
    Patent number: 9112065
    Abstract: A method for encapsulating solar cells includes a curing step that renders CIGS or other types of solar cell absorber layers resistant to degradation by high-temperature lamination processes. The curing process takes place after IV test and prior to the lamination of an encapsulant film. The curing step is carried out in conjunction with a light soaking step that takes place prior to the IV test. The curing process takes place for a time that may range from 10 minutes to two days and at a high relative humidity, RH. Relative humidities of 20-90% are used and have been effective in passivating selenium vacancy defects associated with the absorber layers. The cured absorber layers are resistant to degradation and produce a solar cell with a high solar cell efficiency.
