The method of ionisation potential (dopant contrast) microscopy in the HRSEM is applied to the study of the electric field distribution in p-i-n structures used as quantum well solar cells. Our results show a secondary electron signal which varies be

The inclusion of quantum wells in p-i-n solar cells leads to both an increase in photocurrent and a reduction in open circuit voltage. It has been shown that up to 50 shallow strain-balanced GaAsP/InGaAs quantum wells can be inserted into a GaAs cell

GaInP/GaAs tandem cells are limited by the current generated in the bottom GaAs junction. Strain-balanced multi-quantum well (MQW) solar cells offer a way of achieving a lower band gap for the lower junction, whilst retaining the lattice parameter of

This review starts with the modelling of dark-currents in lattice-matched quantum well cells. We discuss an unexpected result obtained by extending studies of radiative recombination in single wells in the dark to light biased measurements. New resul

The effect of increasing the number of quantum wells in a strain-compensated, multiquantum-well solar cell is investigated. It is found that as the well number is increased, dark current level close to the operating point rises linearly. Short-circui

Multi-quantum well (MQW) cells extend the absorption of bulk gallium arsenide cells to longer wavelengths, increasing short-circuit current and have been shown to exhibit a similar dark current to their p-i-n control cells. To complement the recent a

The exceptional power conversion efficiency of monolithic multi-junction solar cells requires careful current matching in the individual junctions. It is shown that the bulk GaInP/GaAs tandem configuration is not optimal for solar conversion. A means
