What is the efficiency?
Over the past years, organic solar cells have shown steady development. Heliatek set several efficiency records with over 13% cell efficiency.
Nowadays, Chinese researchers have claimed 17% efficiency. However, these numbers are lab results for the smallest cells under optimal conditions.
What truly matters is the re-productivity and transformation into real-life products that are usable and reliable. In this field, Heliatek remains the leading company worldwide.
Their first commercial product HeliaSol® is target around 8% efficiency. The efficiency will be increased gradually up to 20% in the future.
