text: Yo, check it out, listen up, I got something to say,
  About them Perovskite solar cells, they're makin' waves today.
  PSCs, the future of solar, a promising tech,
  Generating electricity, nothin' but respect.
  
  NiO x, an inorganic p-type semiconductor,
  Used widely to stabilize the PSCs, no brainer,
  But the methods to make 'em large and in charge,
  Still need some work, gotta take it far and large.
  
  Enter magnetron sputtering, industry's claim to fame,
  A technique so established, it's got a big name.
  It satisfies the requirements, no need to doubt,
  For manufacturin' large and high-performance clout.
  
  Sputtered NiO x PSCs, they face some limitations,
  Low fill factor, short-circuit current frustrations.
  But fear not, we got a solution, listen well,
  Magnesium doping and low oxygen, they break the spell.
  
  The PSCs we fabricate, they're off the charts,
  With a power conversion efficiency, reachin' 18.5 percent, it imparts.
  No hysteresis, improved stability, and reproducibility,
  These babies got it all, it's a sight to see.
  
  And don't forget, over an area of 100 cm², they're uniform,
  Consistency and quality, they're the norm.
  This simple approach, it's reliable and grand,
  Pavin' the way for commercialization, takin' a stand.
  
  So there you have it, PSCs makin' moves,
  With magnetron sputtering, we're in the groove.
  A rap about solar cells, ain't that neat?
  Keep an eye on PSCs, they can't be beat!
