Solar Frontier achieves record 19.7% CIS efficiency
Solar Frontier, in joint research with Japanís New Energy and Industrial Technology Development Organization (NEDO), has achieved a world record-breaking energy conversion efficiency of 19.7% for cadmium-free, thin-film solar cells measuring approx. 0.5 cm2, as measured by the National Institute of Advanced Industrial Science and Technology (AIST).
It has been ten years since the previous record of 18.6% was surpassed.
This world record was achieved using cells cut from a 30cm x 30cm substrate, rather than specifically-developed small area cells, demonstrating high potential for further increases. Moreover, the formation method utilized by Solar Frontier to achieve the result is the same method it uses for mass-production, a process of sputtering followed by selenization. Solar Frontier has chosen this method over co-evaporation due to greater efficiencies in mass production and aims to surpass the current record of 20.3% efficiency set with the co-evaporation method.
