Abstract :
The polarization-transmissive thin-film solar cell, which consists of a 400 nm-wide silicon photodiode-nanowire grid, transmits the light polarized in one direction and generates photocurrent from the light polarized in the other direction. It can efficiently use light in the system which uses polarization. The fabricated device generated 52 nA photocurrent from the 250 muW incident light by a fluorescent light and achieved the extinction-ratio of 4 for the incident light whose wavelength was 675 nm.
