HIGHLY EFFICIENT PHOTOELECTRIC DEVICE SENSITIZED TO AN INORGANIC/ORGANIC HETEROJUNCTION, INORGANIC SEMICONDUCTOR, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a photoelectric device for a solar cell, having a novel structure and good photoconversion efficiency by including a hole conductive layer having an electron channel forming material/hole conductive polymer, and to a method for manufacturing same. More particularly, the present invention relates to a highly efficient photoelectric device including an electron transport layer, a light-absorbing layer, and a hole conductive layer, and to a method for manufacturing same. In the device, a hole conductive polymer, having the capability of absorbing light in a wavelength range from visible light to near-infrared light and having a hole-conducting capability, may absorb light competitively with the light-absorbing layer or may absorb light having a long wavelength that is not absorbed by the light-absorbing layer so as to produce excitons which are electron-hole combinations. In this case, electrons may be transported through the electron channel.
