The incident photon to electron conversion efficiency up to 84 34% was achieved, which is notably high for cells employing pure organic dyes. To circumvent the sealing difficulties present in wet type cells, the solid state cell was fabricated using poly(ethyleneoxide)(PEO) based gel network polymer electrolyte as charge transfer material between two electrodes. The resulting solid state cell had an energy conversion efficiency of 0 86%, with open circuit voltage of 0 53 V and short circuit current density of 0 96 mA/cm 2 under 38 1 mW/cm 2 white light illumination. The results show that the gel network polymer electrolyte is appropriate for assembling solid state photoelectrochemical cells.展开更多

A key to the subgenera and species of male Chinese Lytta is given. A newly recorded species for China, Lytta （Asiolytta） selanderi Saha is described. The subgeneric assignments for two species are proposed： Lytta （Lytta） battonii （Kaszab） and Lytta （Lytta） sifanica （Semenov）. 23 known species of Chinese Lytta are listed.展开更多
