A simple circuit measuring the relative intensities of the two light sources

Question: Whether it is possible to measure the difference between two light sources using a measuring amplifier? Answer: Yes, by replacing the resistor in the loop measuring amplifier two photoresist. In many situations, the measurement of the relative intensity of the two light sources is more important, than measuring the intensity of each individually. thanks… Continue Reading

Solar energy is becoming an organic

Organic solar cells are typically composed of various organic components, with the necessary semiconductor properties. In contrast to the conventionally used silicon, which is manufactured using energy-intensive melting processes, organic materials are relatively inexpensive because of the lower costs of production and materials, and… Continue Reading
