Abstract: A wide range of temperature control equipment for controlling a tested object to a predetermined temperature is provided. The wide range of temperature control equipment includes a thermal conducting plate, a temperature regulating module, a carrier plate, and a thermoelectric cooling module. The temperature regulating module is thermally connected to the thermal conducting plate for regulating the thermal conducting plate to a reference temperature. The carrier plate is used to accommodate the tested object. The thermoelectric cooling module is thermally connected between the thermal conducting plate and the carrier plate for controlling the tested object to the predetermined temperature via the carrier plate based on the reference temperature.

Abstract: An output control method for a controller includes the following steps. At each of detection time points, the controller detects a detection voltage value and a detection current value of a load. In a voltage control mode, the controller generates a setting parameter to control the power amplifier according to part of the detection voltage values. In a current control mode, the controller generates the setting parameter to control the power amplifier according to part of the detection current values. When the controller switches to the voltage control mode or the current control mode, the controller determines a ratio between the detection current value and the detection voltage value at one of the detection time points and the setting parameter is generated according to the ratio. Therefore, the bandwidth is substantially the same no matter if the controller operates in the voltage control mode or the current control mode.

Abstract: A contact detection circuit is applied to a four-terminal measurement device. The contact detection circuit comprises a first isolator, a signal generator, a multiplier and a calculator. The first isolator comprises a primary side and a secondary side, with the secondary side comprising a first terminal and a second terminal, with the first terminal configured to be electrically connected to a driving terminal and the second terminal configured to be electrically connected to a measuring terminal. The signal generator is configured to provide a measuring signal. The multiplier is configured to generate an output signal based on the measuring signal and a first reflected signal when the first reflected signal is induced at the primary side of the first isolator based on the measuring signal. The calculator calculates contact resistance between the driving terminal and the measuring terminal based on a direct-current component of the output signal.

Abstract: A solar cell testing system includes a multifunctional testing light source, a measuring unit, and an arithmetic unit. The multifunctional testing light source is configured to be switched to output a simulated solar light to a solar cell or asynchronously output a plurality of narrowband lights to the solar cell. The measuring unit is coupled to the solar cell and measures the solar cell's response to the simulated solar light and response to the asynchronously outputted narrowband lights. The arithmetic unit is coupled to the multifunctional testing light source and the measuring unit; it determines the solar cell's conversion efficiency and spectral response based on the solar cell's response to the simulated solar light and response to the asynchronously outputted narrowband lights.
