Mixed cation perovskite solar cells are useful for a satellite mission!
"Our study focused on two typical perovskite compositions, which are mixed cation/halide perovskites CsxFA0.85MA0.15Pb(I0.85Br0.15)3 (x < 0.05) (Saliba et al., 2016a; Singh and Miyasaka, 2017), abbreviated as FAMAPb(IBr)3, and Cl-doped MAPbI3-xClx (Lee et al., 2012), where MA and FA are methylammonium and formamidinium cations, respectively."
"Excellent device stability has been demonstrated on CsxFA1−xPbIyBr3−y, which is the first reported perovskite passing the International Electrotechnical Commission (IEC) 61215 damp heat test (less than 10% PCE decay at 85 °C and 85% relative humidity for 1000 h), a standard accelerating lifetime testing protocol for crystalline silicon terrestrial photovoltaic modules."
