Abstract :
The recently introduced BOSCO (“Both Sides Collecting and Contacted”) solar cell exhibits emitter regions on front and rear side, which are interconnected by diffused vias. This allows double-sided collection of carriers in the base and bifacial operation while supporting standard module interconnection technology. This work gives a simplified loss analysis of the first batch of large-area multi-crystalline silicon cells. A potential efficiency improvement of 0.9 %abs in front-side efficiency and 25 %rel in rear-side efficiency is expected when implementing imminent technological measures.
