Issue Date: | 2019 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | Solar RRL (online), 3 (4) | Abstract: | Tin oxide nanoparticles are employed as an electron transporting layer in solution-processed polymer solar cells. Tin oxide based devices yield excellent performance and can interchangeably be used in conventional and inverted device configurations. In combination with poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) as a hole transporting layer, tin oxide forms an effective interconnecting layer (ICL) for tandem solar cells. Conventional and inverted tandem cells with this ICL provide efficiencies up to 10.4% in good agreement with optical-electrical modeling simulations. The critical advantage of tin oxide in an ICL in a conventional tandem structure over the commonly used zinc oxide is that the latter requires the use of a pH-neutral formulation of PEDOT:PSS to fabricate the ICL, limiting the open-circuit voltage (V-OC) because of its low work function. The SnO2/PEDOT:PSS ICL, on the other hand, provides a nearly loss-free V-OC. | Notes: | Janssen, RAJ (reprint author), Eindhoven Univ Technol, Mol Mat & Nanosyst, POB 513, NL-5600 MB Eindhoven, Netherlands.; Janssen, RAJ (reprint author), Eindhoven Univ Technol, Inst Complex Mol Syst, POB 513, NL-5600 MB Eindhoven, Netherlands.; Janssen, RAJ (reprint author), Dutch Inst Fundamental Energy Res, De Zaale 20, NL-5612 AJ Eindhoven, Netherlands. r.a.j.janssen@tue.nl |
