Metal mesh: a design that revolutionizes the transparent conducting electrode (TCE) industry and drives the development of flexible optoelectronic technology.

High efficiency and flexible inverted organic solar cells have been fabricated using solution-processed silver nanowire/zinc oxide composite transparent electrodes. The transparent electrodes showed a low sheet resistance of ~13 Ω·sq -1 and high transmittance of ~93% as well as superior mechanical flexibility. Power conversion efficiencies of ~7.57% and ~7.21% were achieved for devices fabricated on glass and plastic substrate, respectively. Moreover, the flexible devices did not show any degradation in their performance even after being folded with a radius of ~480 μm.

A flexible transparent electrode is prepared by thermal pressing of a metal-grid into a plastic substrate. The electro-mechanical reliability of the MGETEs is confirmed by the electrical performance of flexible organic solar cells on the MGETEs.
