Photovoltaic panels instead of photoresistors

Photoresistor

Three photoresistors with scale in mm Large CdS photocell from a street light. A photoresistor is less light-sensitive than a photodiode or a phototransistor.The latter two components are true semiconductor devices, while a photoresistor is a passive component that does not have a PN-junction.The photoresistivity of any photoresistor may vary widely depending on ambient

Photoresistors

Photoresistors are also used for automatic contrast and brightness control in televisions and smartphones. For designing of proximity controlled switch photoresistors are used. Due to the ban on cadmium in Europe, use of Cds and Cdse photoresistors is restricted. Photoresistors can be easily implemented and interfaced with microcontrollers.

Understanding Photovoltaic and Photoconductive

But "photovoltaic" is accepted terminology, whether I like it or not. "Zero-bias mode" is better, I think, because we can use the same TIA with the photodiode in photovoltaic or photoconductive mode, and thus the
