This is the normalized spectral response of a silicon carbide photodiode manufactured by Electro Optical Components. This limited spectral response means that SiC photodiodes do not require optical filtering in systems that must prevent visible or infrared light from interfering with UV measurements.
Data are given on the load and spectral characteristics of silicon photocells with p- n junctions, as well as on the operation of these photocells at high intensities of illumination. This paper presents the results of investigations into the properties of p- n junctions obtained by the thermal diffusion of phosphorus into p- type silicon.
