Abstract
A method for cleaning a photovoltaic module, the photovoltaic module having a first electrode layer formed on an insulating substrate, a photovoltaic layer, and a second electrode layer. The laminate is electrically divided between a power generating region and peripheral regions by means of grooves. The power generating region is divided into a plurality of photovoltaic cells by means of laser-scribed grooves. At least some of the photovoltaic cells are connected electrically in series with one another. The cleaning method includes 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.
