Photodetector and photodetecting system capable of detecting information about the two-dimensional intensity distribution and wavelength distribution of incident light

   
   

A photodetector which has the function of measuring the intensity distribution of light with a simple and inexpensive construction and which has a selectivity for a measured wavelength band. The photodetector includes a transparent semiconductor electrode part and counter electrode part on each of which a sensitizing dye is applied, and a buffer layer sandwiched therebetween. The counter electrode part or the transparent semiconductor electrode part is divided into a plurality of electrode cells. Thus, it is possible to realize a compact photodetector which carries out a photoelectric transfer using part of light in a wavelength band absorbed into the sensitizing dye and which has a wavelength selectively.

Um photodetector que tenham a função de medir a distribuição da intensidade da luz com uma construção simples e barata e que tenha um selectivity para uma faixa medida do wavelength. O photodetector inclui uma peça transparente do elétrodo do semicondutor e a peça do elétrodo contrário em cada um de que uma tintura sensitizing é aplicada, e uma camada do amortecedor imprensada therebetween. A peça do elétrodo contrário ou a peça transparente do elétrodo do semicondutor são divididas em um plurality de pilhas do elétrodo. Assim, é possível realizar um photodetector compacto que realizem transferência fotoelétrica usando a parte da luz em uma faixa do wavelength absorvida na tintura sensitizing e que tenha um wavelength seletivamente.
