How much do multi-junction solar cells cost? Cost of multi-junction solar cells are difficult to estimate, owing to the variance in the number of cells considered, and also owing to the nascent nature of this sector. However, it can be safely said that as of 2014, multi-junction solar cells cost at least 2-2.5 times as much as single junction ...
The top cell characteristics depend on the minority carrier lifetime in the top cell layers.

In the last decade, photovoltaics (PV) has experienced an important transformation. Traditional solar cells formed by compact semiconductor layers have been joined by new kinds of cells that are constituted by a complex mixture of organic, inorganic and solid or liquid electrolyte materials, and rely on charge separation at the nanoscale.
An electroluminescence (EL) anomaly singular spot was observed in an industry-standard InGaP/GaAs multi-junction solar cell (MJSC). Affected by this singular spot, the spatially resolved subcell current distributions were found to exhibit unique opposite characteristics, which we call "defect-induced current coupling."
