1. A liquid crystal device comprising:
a first portion,
a second portion, and
a liquid crystal layer;
wherein:
said first portion includes a first substrate, said first substrate being at least partially covered by a first electrode layer;
said second portion includes a second substrate, said second substrate being at least partially covered by a second electrode layer;
at least one of said first and second electrode layers includes a plurality of electrodes that are electrically insulated from each other;
the at least one of said first and second electrode layers is at least partially covered by at least one photovoltaic semiconductor conversion layer;
the at least one of said first and second portions is transparent;
said first portion is substantially parallel to said second portion; and
said liquid crystal layer is disposed between said first and second portions,
wherein a first photovoltaic conversion semiconductor layer is arranged between said first electrode layer and said liquid crystal layer and/or a second photovoltaic conversion semiconductor layer is arranged between said second electrode layer and said liquid crystal layer, wherein the photovoltaic conversion semiconductor layer deposited on the first portion is a conventional PV layer, whereas the photovoltaic conversion semiconductor layer deposited on the second portion is an inverted PV layer.
