Ionic liquid electrolyte
The present invention relates to electrolytes comprising tetracyanoborate and an organic cation as components of electrolytes in electrochemical and/or optoelectronic devices, in particular solar cells. This ionic liquid has low viscosity and can be used as electrolyte in the absence of a solvent. Importantly, the ionic liquid remains stable in solar cells even after prolonged thermal stress at 80 DEG C for 1000 hours. Photovoltaic conversion efficiency remained stable and keeping more than 90% of the initial value.
