Effect of annealing temperature on the performance of printable carbon electrodes for perovskite solar cells

Mohammad Khaja Nazeeruddin, Iwan Zimmermann

Perovskite solar cells (PSCs) with mesoporous TiO2 electron transport layers have reached > 22% efficiency at laboratory scale ( < 1 cm(2)), however, these layers are fabricated using spin-coating, which is not conducive to large-scale or high throughput f ...

ELSEVIER SCIENCE BV2019

Gravure printed Ag/conductive polymer electrodes and simulation of their electrical properties

Frank Nüesch, Jakob Heier, René Uwe Schneider

In this paper, some practical issues related to the manufacturing, and design criteria related to the application in devices of a hybrid silver grid/poly (3,4-ethylenedioxythiophene) semi-transparent electrode are discussed. The electrodes are fabricated b ...
