Why has Epishine chosen to focus on organic solar cells (OPV) instead of dye-sensitized solar cells (DSSC)?
Epishine has chosen to focus on organic photovoltaics (OPV) instead of dye-sensitized solar cells (DSSC) as OPV is generally considered better suited for indoor applications, product integration, and particularly scalable manufacturing.
Organic solar cells use a solid-state device structure, meaning they do not rely on liquid components. In contrast, dye-sensitized solar cells are electrolyte-based, where liquid materials are used for charge transport. A solid-state design simplifies integration into everyday electronic products and avoids the need for complicated, costly and hard-to-scale encapsulation of liquid components inside the device. The retained liquid state in the device is a considerable increase in a production environment translating to higher costs via yield and throughput limitations.
From a manufacturing perspective, organic solar cells can be produced using low-temperature, roll-to-roll processes, enabling scalable and cost-efficient high-volume production. This makes the technology well suited to meet the growing demand for low-power electronics.
