Three automatic bias controls were developed for use with silicon photovoltaic cells when operated with background flux present. One of these completely eliminates signal degradation even under very high background intensities. The transistorized version could be greatly improved by using field effect transistors and other recent developments in circuitry to reduce the noise level. Measurements were made of various properties of germanium photovoltaic diodes. The number at hand was small but all of them indicated that the degradation in signal with high background flux appears to increase with cell sensitivity. Automatic back-biasing appears necessary for optimum noise equivalent power. Author
