Hot-carrier solar cells (HCSCs) are one option for achieving solar-energy conversion more efficiently than conventional single-junction cells. Due to challenging material requirements, the development of HCSCs has been limited proof-of-concept devices. By examining heat flow in HCSCs, this study suggests expanding their characterization include carrier temperatures various contact configurations and biases. The authors show that hotter is not always better: High may be a sign excessively high barriers extraction---an insight could adjust expectations interpretations hot-carrier
