1. a kind of photovoltaic devices, including light acquisition equipment and photovoltaic cell;

  • Wherein described smooth acquisition equipment includes organic semiconductorPhotoactive layer, the organic semiconductor photoactive layer can be produced with the luminescent material being dispersed therein come many excitons;

    Wherein instituteThe band gap for stating luminescent material is chosen to three formed because the described many excitons in the organic semiconductor are producedWeight state exciton can be transferred in the luminescent material via dexter energy transfer by on-radiation;

    Photovoltaic cell is arrangedIn the transmitting light path of the luminescent material and with the first photoactive layer, wherein the band gap of the luminescent material and describedThe band-gap of one photoactive layer or the band gap higher than first photoactive layer.
