Summary
Energy level diagrams of metal contacts to silicon solar cells are examined, as well as equations governing the tunneling conductance. Symptoms of some solar cell contact problems are mentioned and potential diagnoses are suggested. These include the “flat spot” phenomenon and “S” shaped curves along with the more common series and shunt resistance problems, which all result in poor fill factor and consequently lower efficiencies. Examination of recent solar cells provided with screened thick film copper contacts along with controls, indicate that this contact method does not impose an efficiency limitation.
