Abstract

Various approaches for the realization of transparent photodiodes based on bulk heterojunction blends of poly-3-hexylthiophene and [6,6]-phenyl butyric acid methyl ester are examined. Results suggest the transmittance of 36 percent of the incident light with 46 percent external quantum efficiency (EQE) at a wavelength of 530 nm.

Abstract

Solution-processed photodiodes with infrared sensitivities at wavelengths beyond the bandgap of silicon would be a significant advance towards cost-effective imaging. Colloidal quantum dots are highly suitable as infrared absorbers for photodetection. The concept of organic bulk heterojunctions sensitized with PbS nanocrystalline was proved with efficient near-infrared detection up to 1.8 mm for NIR imaging on active matrix TFT backplanes and demonstrated x-ray sensitivity.

Abstract

The growing interest in short-wavelength infrared (SWIR) imagers is related to the increasing number of applications in this particular spectral region. Wavelengths between the silicon bandgap limit of about 1.1 [...]
