Method for removing peripheral region of functional layers in e.g. thin-film solar module, involves irradiating laser on substrate of photovoltaic module for removing peripheral region of functional layers in photovoltaic module

摘要

The method involves irradiating laser on substrate (11) of photovoltaic module (1) for removing peripheral region of functional layers (10) in photovoltaic module. A wavelength of irradiating laser is greater than or equal to 266 nm and less than or equal to 400 nm. A pulse duration of irradiating laser is less than or equal 100 ns and longer or equal to 100 ps.
