| 摘要 |
A semiconductor liquid junction photocell using a photoactive electrode comprising GaAs has greatly improved solar energy to electrically conversion efficiency when compared to prior art semiconductor liquid junction photocells using GaAs electrodes. The improved efficiency is obtained by material, such as ruthenium, cobalt, rhodium or lead, on the electrode surface. Efficiency is still further increased by texturizing the surface of the GaAs electrode prior to addition of the material. Efficiencies under AM1 conditions are approximately 12 percent. |
