Is perovskite technology a future for solar energy?
The gradual integration of perovskite technology suggests a promising future for solar energy, combining the best of both worlds to drive innovation and sustainability. The commercial viability of PSCs and tandem solar cells depends on a thorough assessment of their long-term stability under real-world conditions.
What is a perovskite solar cell?
The name "perovskite solar cell" is derived from the ABX 3 crystal structure of the absorber materials, referred to as perovskite structure, where A and B are cations and X is an anion. A cations with radii between 1.60 Å and 2.50 Å have been found to form perovskite structures.
What are tin-lead perovskite absorbers?
A major development in this area is the manufacture of tin–lead (Sn-Pb) perovskite absorbers, which can serve as the bottom cell in tandem solar cells . These materials have band gaps in the range of 1.2–1.3 eV, making them perfect for absorbing the low-energy part of the solar spectrum.
