针对无线电能传输的广泛应用，研究了垂直腔面发射激光器（VCSEL）阵列与单晶硅太阳能电池之间975 nm波长的光无线电能传输。测得该电池的发电效率高达33%，这高于用太阳光照射时的效率18%。这主要是因为传输损耗被消除了。然而，太阳能电池的电阻的进一步减小是必要的，因为效率随着入射能量的增加而降低。
Aiming widespread use of wireless power transmission, optical wireless power transmission at wavelength of 975 nm between vertical cavity surface emitting laser (VCSEL) arrays and a single crystalline Si solar cell was studied. The power generation efficiency of the cell was measured as high as 33% which was higher than the efficiency of 18% at the time of irradiation with sunlight. This is because the transmission loss is mainly eliminated. However, further reduction of the electrical resistance of the solar cell is necessary because the efficiency decreases with increasing incident energy.
