Why does Epishine focus on indoor solar cells?

Most wireless low-power electronics operate indoors, where light levels are significantly lower than outdoors. Traditional solar cells are designed for direct sunlight and perform poorly in low-light conditions. 

Epishine develops indoor solar cells (indoor photovoltaics, IPV) specifically optimized to capture low indoor light efficiently. Our technology delivers reliable performance where most other solar cells generate very little power. 

Epishine combines low-light optimized advanced photonic materials with roll-to-roll manufacturing — enabling a new manufacturing paradigm for electronics: scalable, cost-efficient, and sustainable.
