Abstract

Thin-film solar cells based on hybrid organo-halide lead perovskites achieve
over 22% power conversion efficiency (PCE). A photovoltaic technology at
such high performance is no longer limited by efficiency. Instead, lifetime and
reliability become the decisive criteria for commercialization. This requires a
standardized and scalable architecture which does fulfill all requirements for
larger area solution processing. One of the most highly demanded technologies
is a low temperature and printable conductive ink to substitute evaporated
metal electrodes for the top contact. Importantly, that electrode technology
must have higher environmental stability than, for instance, an evaporated
silver (Ag) electrode. Herein, planar and entirely low-temperature-processed
perovskite devices with a printed carbon top electrode are demonstrated. The
carbon electrode shows superior photostability compared to reference devices
with an evaporated Ag top electrode. As hole transport material, poly (3′hexyl
thiophene) (P3HT) and copper(I) thiocyanate (CuSCN), two cost-effective
and commercially available p-type semiconductors are identified to effectively
replace the costlier 2,2′,7,7′-Tetrakis-(N,N-di-4-methoxyphenylamino)-
9,9′-spirobifluorene (spiro-MeOTAD). While methylammonium lead iodide
(MAPbI3)-based perovskite solar cells (PSCs) with an evaporated Ag electrode
degrade within 100 h under simulated sunlight (AM 1.5), fully solution-processed
PSCs with printed carbon electrodes preserve more than 80% of their
initial PCE after 1000 h of constant illumination.
