Perovskite solar generator

What are perovskite solar cells?

Perovskite solar cells are one of the most active areas of renewable energy research at present. The primary research objectives are to improve their optoelectronic properties and long-term stability in different environments.

Are perovskite/Si solar cells degraded?

They found that monolithic perovskite/Si solar cells became severely degraded, maintaining only 1% of their initial PCE, which compared poorly to perovskite/CIGS tandem solar cells that retained 85% of the initial PCE under space solar illumination conditions (AM0).

Can a perovskite solar cell and a supercapacitor be integrated?

Liu, Z. et al. Novel integration of perovskite solar cell and supercapacitor based on carbon electrode for hybridizing energy conversion and storage. ACS Appl. Mater.

Are all-perovskite tandem solar cells efficient?

Xiao, K. et al. All-perovskite tandem solar cells with 24.2% certified efficiency and area over 1 cm 2 using surface-anchoring zwitterionic antioxidant. Nature Energy 5, 870–880 (2020). Tong, J. et al. Carrier lifetimes of >1 μs in Sn-Pb perovskites enable efficient all-perovskite tandem solar cells.

Are halide perovskites a new class of solar cells?

Nature Photonics 8, 506–514 (2014) Cite this article The past two years have seen the unprecedentedly rapid emergence of a new class of solar cell based on mixed organic–inorganic halide perovskites.

Why do perovskite/Si solar cells lose PCE?

The poor device stability of monolithic perovskite/Si solar cells was ascribed to the radiation-induced formation of recombination centers in the Si. It was also found that the primary reason for the PCE loss in perovskite/CIGS tandem solar cells was due to increased recombination in the CIGS subcell.
