Infrared photocarrier radiometry, modulated photovoltage and electrical characteristics of polycrystalline Si solar cells

Laser-induced infrared photocarrier radiometry (PCR) was used to characterize industrial polycrystalline silicon solar cells. The ac photovoltage was measured simultaneously with the PCR signal. The PCR and ac photovoltage signals were investigated as functions of modulation frequency, excitation in...

Description
Summary:Laser-induced infrared photocarrier radiometry (PCR) was used to characterize industrial polycrystalline silicon solar cells. The ac photovoltage was measured simultaneously with the PCR signal. The PCR and ac photovoltage signals were investigated as functions of modulation frequency, excitation intensity, external dc illumination and load resistance. The interrelation and interpretation of PCR signal, ac photovoltage and static (dc) electrical parameters of solar cells are discussed.
