Abstract:Kupari on yleinen alkuaine, ja siten hankalasti kontrolloitava epäpuhtaus piikomponenttien tuotantolinjoilla. Jo hyvin pienet kuparikonsentraatiot p-tyypin piikomponenteissa (esim. aurinko- kennoissa) voivat johtaa kuparin aiheuttamaan valodegradaatioon, eli vähemmistövarauksen- kuljettajien bulkkielinajan lyhenemiseen ylimäärävarauksenkuljettajainjektion aikana. |
