In the research published in Joule, researchers identify the source of the corrosion in the low-band-gap cells and introduce nonconventional hole-transfer layer with a caroboxyl group with a higher acid disassociation constant. This new hole-transfer layer suppresses the deprotonation process that causes the corrosion and ultimately extends the lifespan of the tandem unit to more than 1,000 hours with an efficiency loss of less than 3%.
