Lo scopo del presente lavoro è quello di preparare e caratterizzare film di elettroliti solidi polimerici drogati con ioduro di ammonio e le loro applicazioni nella fabbricazione di celle solari sensibilizzate con coloranti (DSSC). I tre sistemi elettrolitici polimerici, ovvero (1) alcool polivinilico (PVA) drogato con ioduro di ammonio (NH4I), (2) pirolidone polivinilico (PVP) drogato con NH4I e (3) metacrilato polietilico (PEMA) drogato con NH4I, sono stati preparati, caratterizzati e utilizzati per la fabbricazione di DSSC.

Ziel der vorliegenden Arbeit ist die Herstellung und Charakterisierung von mit Ammoniumiodid dotierten Polymer-Festkörperelektrolytfilmen und ihre Anwendung bei der Herstellung von Farbstoffsolarzellen (Dye Sensitized Solar Cells, DSSCs). Die drei Polymerelektrolytsysteme, nämlich (1) mit Ammoniumiodid (NH4I) dotierter Polyvinylalkohol (PVA), (2) mit NH4I dotiertes Polyvinylpyrrolidon (PVP) und (3) mit NH4I dotiertes Polyethylmethacrylat (PEMA), wurden in dieser Untersuchung hergestellt, charakterisiert und für die Herstellung von DSSCs verwendet.
