Betanin dye extracted from ayrampo ( <i>Opuntia soehrensii</i> ) seeds to develop dye-sensitized solar cells

Abstract

the addition of citric acid to stabilise the photosensitive dye, and an efficiency of 1.41% was achieved with current output remaining stable after 7 days. Upon testing in low-light conditions, the solar conversion efficiency of devices increased to 4%. This paper not only highlights the potential of natural sensitizers in DSSCs but also shows that simple extraction and gentle handling methods can contribute to the device performance.
