Photovoltaics ldquoPhotovoltaics is the most direct way to
convert solar radiation into electricity and is
based on the photovoltaic effect which was
first observed by Henri Becquerel in 1839
hellipgenerally defined as the emergence of an
electric voltage between two electrodes
attached to a solid or liquid system upon
shining light onto this system Practically all
photovoltaic devices incorporate a pn
junction in a semiconductor across which the
photovoltage is developedrdquo Goetzberger

Solar cells Efficiencies
bull The absorber layer of an

molecules
Donors Conjugated polymers oligomers or conjugated
pigments
Acceptors Fullerene derivatives
They are known for their outstanding optical properties
and their ability to transport charges
