Hello I am trying to fabricate a Si reflecting solar cell. When a Solar cell is exposed to radiation and connected to external circuit, the current will start to flow through the circuit. So I want to know how does the Reflectivity of silicon change with the current( or conductance).[ Initially when solar cell is irradiated but not connected to circuit, the current is zero. when connected to external circuit, current rises. So how does the reflectivity change with change in current] If the question is not clear please let me know Thank you in advance for your help.
