Fully printable flexible perovskite solar cell achieves 17.6% efficiency

Developed by scientists in Canada, the 0. 049 cm2 solar cell was built in ambient air fabricationand with a reactant known as phenyltrimethylammonium chloride (PTACl). It achieved an open-circuit voltage of 0. 95?V, a short-circuit current density of 23?mA?cm-2, and a fill factor of 80%. Researchers at the University of Victoria in Canada have built a flexible perovskite solar cell based on a polyethylene terephthalate (PET) substrate in ambient air fabrication. They explained that PET is cheaper than commonly utilized polyethylene naphthalate (PEN) in substrates for flexible solar cells, with ...
