A well-designed silicon heterojunction module has an expected nominal lifespan of more than 30 years, with an expected average performance ratio of 75%. Failure, power losses and degradation of SHJ cells and modules can be categorised by the affected parameter (eg. open-circuit voltage, short-circuit current and fill factor). losses are generally attributed to reduction in passivatio.
