It is found that effective diffusion length is controlled by the grain size d and the space-charge potential barrier height at the grain boundary. The dependence of effective minority-carrier diffusion length and space-charge potential barrier height on the grain size is also investigated theoretically. The theory predicts that, for large grain sizes, the effective diffusion length is approximately proportional to d1/2, while for small grain sizes it is proportional to d. The available experimental data are found to be in good agreement with the theoretical predictions. Abstractde Es wird eine neue Beziehung angegeben für die effektive Minoritätsträger-Diffusionslänge in polykristallinem Silizium unter Sonnenbestrahlung. Es wird gefunden, daß die effektive Diffusionslänge durch die Korngröße d und die Höhe der Raumladungspotentialbarriere an den Korngrenzen gesteuert wird. Die Abhängigkeit der effektiven Minoritätsladungsträgerdiffusionslänge und denr Höhe der Raumladungspotentialbarriere von der Korngröße wird auch theoretisch analysiert. Die Theorie ergibt, daß für große Kornabmessungen, die effektive Diffusionslänge näherungsweise zu d1/2 proportional ist, während sie für geringe Korngrößen proportional zu d ist. Es wird gefunden, daß vorhandene experimentelle Werte in guter Übereinstimmnng mit den theoretischen Vorhersagen sind. References 1 T. L.
