Disorder-engineered inorganic nanocrystals set a new efficiency record for ultrathin solar cells

https://phys.org/news/2022-02-disorder-engineered-inorganic-nanocrystals-efficiency-ultrathin.html

"set a record among low-temperature and solution processed, environmentally friendly inorganic solar cells in terms of stability, form factor and performance. The engineering of the multinary systems with cation disordered AgBiS2 colloidal nanocrystals has proven to offer an absorption coefficient higher than any other photovoltaic material used to date, enabling highly efficient extremely thin absorber photovoltaic devices"
