Presented at: Symposium on the efficient use of solar radiation in photovoltaic power engineering, St. Petersburg, Russia, 3-4 november 2003.
Abstract:
A planar converter containing quantum dots as wavelength-shifting moietieson top of a solar cell was studied. The highly efficient quantum dots
are to shift the wavelengths where the spectral response of the solar
cell is low to wavelengths where the spectral response is high in order
to improve the conversion efficiency of the solar cell. It was calculated
that quantum dots with an emission at 603 nm increase the multicrystalline
solar cell short-circuit current by nearly 10%. Simulation results for
planar converters on hydro-generated amorphous silicon solar cells show
no beneficial effects, due to the high spectral response at low wavelength.
