Abstract

A scalable, hysteresis-free and planar architecture perovskite solar cell is presented, employing a flame spray synthesized low-temperature processed NiO (LT-NiO) as hole-transporting layer yielding efficiencies close to 18%. Importantly, it is found that LT-NiO boosts the limits of open-circuit voltages toward an impressive non-radiative voltage loss of 0.226 V only, whereas

Pedot: PSS suffers from significant large non-radiative recombination losses.

Keywords: low temperature processing; nickel oxide; non-radiative voltage loss; perovskite solar cells.
