In recent years the potential induced degradation (PID) of photovoltaic modules (crystalline and thin film) has attracted a strong interest, as it turned out that PID occurs frequently in PV systems and solar parks. PID is the loss of system power initiated by leakage currents at high voltages. The phenomenon occurs most commonly in photovoltaic (PV) modules that are closest to the negative pol when...
Terahertz time-domain spectroscopy can be used to characterize silicon solar cell properties such as: conductivity, charge carrier mobility and density. Moreover, THz spectroscopy and imaging can be used for defect analysis in semiconductor and photovoltaic materials. This paper describes the investigation of optically injected charge carrier dynamics by the use of THz spectroscopy. THz-pump/THz-probe...
