A cleaning device and a sweeper, the cleaning device includes a driving module, which includes a lifting driver; a lifting module, which includes a first shaft sleeve and a second shaft sleeve, the first shaft sleeve is connected with a power output shaft of the lifting driver, a screw mechanism is formed between the first shaft sleeve and the second shaft sleeve; and a cleaning module, which includes a cleaning member connected with the second shaft sleeve; the screw mechanism is at least is subjected to a first driving force of the power output shaft of the lifting driver to drive the cleaning member to perform a descending motion relative to the lifting driver, and is subjected to a second driving force to drive the cleaning member to perform an ascending motion relative to the lifting driver.

Cleaning device, cleaning mechanism, sweeper and cleaning apparatus

Provided are a heterojunction solar cell film deposition apparatus, method and system, a solar cell, a module, and a power generation system. The heterojunction solar cell film deposition apparatus is configured for amorphous silicon-based film deposition, and comprises a loading chamber, a preheating chamber, intrinsic process chambers, doping process chambers and an unloading chamber that are linearly arranged in sequence, the chambers being isolated from each other by means of an isolating valve. At least two intrinsic process chambers are provided and are configured for deposition by means of an intrinsic layer silicon film process; and at least one doping process chamber is provided and is configured for deposition by means of an N-type silicon film or P-type silicon film process. The preheating chamber comprises a heating preheating chamber and a preheating buffer chamber that is configured for adjusting the gas and pressure atmosphere.
