Employing its liquid-based dye solar cell (DSC) substrate, Dyesol claimed it had surpassed the standard IEC 61646 design qualification for PV modules, without disclosing the approved testing house.
The IEC 61646 testing standard was mainly based on amorphous silicon (a-Si) technology, designed to monitor such module’s performance (Pmax) capabilities under prolonged exposure to ‘standard’ climates.

Dysol said that its liquid-based dye solar cell (DSC) substrate maintained over 90% of the initial performance after a 5000 hour cycle at 85 C. The company said that the IEC 61646 standard called for 1,000 hours and 85C.
The company recently claimed a breakthrough with a ‘solid state’ DSC system.
