The photovoltage Voc of high-performance solar cells such as GaAs
and metal halide perovskites is affected by the exponential Urbach tail in the
absorption spectrum, with an energy parameter EU. It has been observed that
increasing Urbach energy decreases the maximum photovoltage that can be
achieved. On the basis of detailed balance and reciprocity of absorption and
emission, we present a calculation that shows that the voltage loss due to the
exponential tail in an absorption obeys a universal relation ΔVoc
rad = (kBT/q) ln(1 −
EU/kBT) for EU < kBT, independently of the bandgap. [-]
