The invention concerns a liquid crystal spatial light modulator () comprising: a liquid crystal layer (); and on at least one side of the liquid crystal layer (), at least one photovoltaic cell (), each photovoltaic cell () comprising a photosensitive layer () comprising electron-donating (D) molecules and electron accepting (A) molecules, each photovoltaic cell () being arranged for spontaneous photovoltage under illumination. Electron-donating molecules and electron accepting molecules are preferably blended and form preferably an organic bulk heterojunction layer. The photosensitive layer () of each photovoltaic cell () is preferably comprised between: &#x2014;an electron conducting layer () arranged for a transfer of an electron from its contacting photosensitive layer () easier than a transfer of an electron hole from its contacting photosensitive layer (), and &#x2014;an electron hole conducting layer () arranged for a transfer of an electron hole from its contacting photosensitive layer () easier than a transfer of an electron from its contacting photosensitive layer ().
