Abstract:
A method for cleaning a photovoltaic module, the photovoltaic module having a laminate including a first electrode layer formed on an insulating substrate, a photovoltaic layer, and a second electrode layer, the laminate being electrically divided between a power generating region and peripheral regions by means of grooves, the power generating region being divided into a plurality of photovoltaic cells by means of laser-scribed grooves, at least some of the photovoltaic cells being connected electrically in series with one another, the cleaning method comprising:a process for transporting the photovoltaic module immersed in a cleaning fluid, while being kept in a horizontal position with the laminate upward as it is transported, and applying ultrasonic vibration to the cleaning fluid, thereby removing particles in the scribed grooves.
