However, optimal light trapping can hardly exceed the Lambertian limit as provided by a random scatterer, except in narrow spectral or angular ranges. The short-circuit current – i.e. the integrated absorptance weighted with the solar spectrum – approaches the maximum value for thicknesses larger than several 10 µm.

A photocell is a light-sensitive device that changes its electrical properties (such as resistance or voltage) in response to incident light. It is commonly used in light sensors, automatic lighting controls, and light meters. Photoelectric, on the other hand, refers to the phenomenon or technique of using light to detect or measure objects.

The fill factor of a silicon photocell is a measure of its efficiency in converting light energy into electrical energy. It is expressed as a percentage and is calculated by dividing the maximum power output of the cell by the product of its open-circuit voltage and short-circuit current.
A photocell is an electronic device that converts light energy into an electric current. It consists of two types of silicon crystal. When light is absorbed by the silicon, negatively charged electrons are knocked loose from the silicon atoms, causing them to flow freely and create an electric current.
When the input light intensity of silicon photocell is constant, the relationship between the output voltage and current of the photocell along with the change of load resistance is called the volt ampere characteristic.
