The solar cell quantum efficiency measurement system is an advanced photovoltaic device test instrument, specifically designed to evaluate and analyze the external quantum efficiency (EQE) of the solar cell. This system can accurately and quickly obtain the monochromatically incident photon-to-current efficiency (IPCE) and the spectral response of the solar cell.
Maximum power point tracking (MPPT) technology for solar cells ensures that the photovoltaic device maintain their maximum output power, when the load or ambient enviroment (e.g. light intensity) change.
