11. His other work has focused on III-V heterojunction devices, and LEDs. 12. The effective fields are set up by creating a heterojunction between two dissimilar materials. 13. The arrangement of materials essentially determines the overall efficiency of the heterojunction solar cell. 14. Typically, a polymer-fullerene bulk heterojunction solar cell has a layered structure. 15. Two closely spaced heterojunction interfaces may be used to confine electrons to a rectangular quantum well. 16. Most bulk heterojunction cells use two components, although three-component cells have been explored. 17. Fig 5 : Highly folded heterojunction ( a ); heterojunction with controlled growth ( b) 18. Fig 5 : Highly folded heterojunction ( a ); heterojunction with controlled growth ( b) 19. Kopin's main product is _ take a deep breath _ a heterojunction bipolar transistor wafer. 20. Band diagrams for a straddling-gap type heterojunction , as understood by Anderson's rule.
