A method for setting addresses of slave devices in a communication network is provided. In the communication network, a master device identifies address-collided slave devices and requests the address-collided slave devices to return their unique identification data. The master device sets addresses of the address-collided slave devices so that each of the slave devices in the communication network has a different address from one another.

A solar cell module includes lower and upper substrates that are spaced apart from each other, a plurality of spaced apart solar cells, a plurality of gratings, and a light-transmissive encapsulant disposed between the lower and upper substrates to encapsulate the solar cells and the gratings. Each of the gratings has a grating center, and four reflecting regions formed around the grating center. Each of the reflecting regions has a light entrance face that has a plurality of valleys and peaks. The valleys and peaks alternate with each other along a direction from the grating center to a corresponding one of the corners of a corresponding one of the four adjacent solar cells.

A method for reducing light-induced-degradation in manufacturing a solar cell, includes the steps of: (a) irradiating the solar cell with an irradiance; (b) maintaining the solar cell within a temperature range; (c) removing the solar cell away from the irradiance of step (a) after a time; and (d) determining the irradiance, the temperature range, and the time such that the LID is optimally below a predetermined LID.

An alternating current (AC) line emulator includes an AC power supply and an automatic regulating load. The AC power supply is used for providing an AC line frequency and an AC line voltage. The automatic regulating load is coupled between the AC power supply and a grid-connected power generation system for functioning as a test load of the grid-connected power generation system, and preventing current from reversing to the AC power supply and shutting down the AC power supply. When the grid-connected power system is tested, power consumption of the automatic regulating load is equal to a sum of output power of the grid-connected power generation system and output power of the AC power supply.
