In the ever-increasing energy demand scenario, the development of novel photovoltaic (PV)
technologies is considered to be one of the key solutions to fulfil the energy request. In this …

The past five years have seen significant cost reductions in photovoltaics and a
correspondingly strong increase in uptake, with photovoltaics now positioned to provide one …

Photovoltaic generation has stepped up within the last decade from outsider status to one of
the important contributors of the ongoing energy transition, with about 1.7% of world …

Robust electronic edge or surface modes play key roles in the fascinating quantized
responses exhibited by topological materials. Even in trivial materials, topological bands …

In a hot carrier solar cell, the steady-state carrier population is hot relative to the surrounding
lattice. This requires an absorber material which restricts carrier–phonon interaction and …

We demonstrate a new hot‐carrier photovoltaic cell based on the resonant tunnelling of hot
electrons from a narrow‐band‐gap semiconductor to a wider‐band‐gap semiconductor. Hot …

An unambiguous observation of hot-carrier photocurrent from an InGaAs single quantum
well solar cell is reported. Simultaneous photo-current and photoluminescence …

Since their advent around the start of the millennium, hot carrier solar cells came into the
focus of a broader research community as one of the so-called third generation photovoltaic …

InAs/AlAsxSb1− x quantum wells are investigated for their potential as hot carrier solar cells.
Continuous wave power and temperature‐dependent photoluminescence indicate a …

Hot-carrier solar cells require absorber materials with restricted carrier thermalization
pathways, in order to slow the rate of heat energy dissipation from the carrier population to …
