Photodiodes are optical sensors that convert the energy of light into electrical energy. Organic photodiodes (OPDs) respond quickly and have the advantage of being able to realize colors free from color filters because they can control the spectral response of wavelengths. However, most of the color controlling methods reported so far do not fit the current trends of small, thin screens because they thicken the photodiodes to cause light distortion. To meet such demands, a POSTECH research team has succeeded in producing thin-film organic photodiodes with an accurate and simple junction engineering.
