The advantage of Si photocells of course is their quite inexpensive cost compared with low bandgap cells such as GaSb, and also their commercial availability in large quantities. Additionally, unlike GaSb or CIGS cells, silicon is a non-toxic material.
In bright light, the photocell’s resistance is around 10 kΩ, making an output of about 2.7 V. In darkness, the photocell’s resistance is around 500 kΩ, making an output of about 0.3 V. The sensor output could go to a PIC32 digital or analog input. Kevin M. Lynch, ... Matthew L. Elwin, in Embedded Computing in C with the PIC32 Microcontroller, 2016

In bright light, the photocell’s resistance is around 10 kΩ, making an output of about 2.7 V. In darkness, the photocell’s resistance is around 500 kΩ, making an output of about 0.3 V.
Under such highly concentrated conditions and hence the existence of elevated current densities, the cells are required to have a sufficiently small series resistance so as to maintain an appropriately high fill factor; otherwise, photocells would suffer further undesired efficiency losses.
