The driving and transmission device consists of the rollers, the motor of conveyor belts and conveyor belts, the cotton pressing device consists of an electric push rod, a connecting rod, a connecting plate, and a high light transmittance glass plate. Said rapid detection system could realize the rapid detection to the impurity rate and moisture regain rate of the seed cotton.

Abstract: The disclosure relates to solar cell, and especially to a method for manufacturing a crystalline silicon solar cell module. The method includes: a) providing a solar cell module to be laminated, including a back plate, a first bonding layer, a crystalline silicon solar cell component, a second bonding layer and a top plate in contact in sequence, where the crystalline silicon solar cell component is a crystalline silicon solar cell or a cell string formed by connecting multiple crystalline silicon solar cells; b) laminating the solar cell module to be laminated under current injection, to obtain a laminated solar cell module; and c) installing a frame and a junction box on the laminated solar cell module, to obtain a crystalline silicon solar cell module. The crystalline silicon solar cell module is under the current injection during the laminating process, improving the performance against light-induced degradation.

Abstract: A device and a method for detecting the ability of anti PID effect of a solar cell are disclosed according to embodiments of the invention. The device includes a static generator including a high voltage power supply and an ion stick connected to the high voltage power supply; and a metal tray under the ion stick. It is judged whether the solar cell has the ability of anti PID effect by detecting the solar cell directly by the device, so for determining whether the solar cell has the ability of anti PID effect, there is no need for a solar cell assembly manufactured by the solar cell.
