The interconnection tech, developed by scientists at the Belgian research institute Imec, is based on a three-dimensional fabric of encapsulant with incorporated horizontal and vertical solder‐coated metal ribbons. Mini solar modules built with the proposed technique have provided interesting results in tests for thermal cycling reliability, showing very limited degradation.
Appetite may have been lacking among private investors – at a time when global stocks are tanking amid Covid-19 and global recession fears – but the eco-friendly new Finnish government, and neighboring administrations, have stepped in to fill the breach.
Researchers in Germany are trialing a host of new processes and materials to develop interdigitated back contact solar cells. A deposition technology named ‘hot-wire’ chemical vapor deposition, is said to provide excellent passivation without the need for treatments such as recrystallization or hydrogenation.
The Finnish PV equipment provider and the Lithuanian PV panel maker will manufacture IBC solar cells at Solitek’s factory in Vilnius with an initial production capacity of 60 MW.
The new record is just 0.24% below the Chinese company’s small-area laboratory cell record and has been achieved on an industrial, large area cell.
