Abstract
A method for repairing and/or optimizing a solar module having a sun-facing front and a sun-averted back, a multiplicity of solar cells being encapsulated between the front and the sun-averted back, the method having the following steps: a) providing a solar module, b) applying a voltage to the provided solar module in the reverse direction, c) locally illuminating and scanning the front of the solar module to which the voltage is applied with a point light source, with the result that a flow of current flows through the solar cells encapsulated in the solar module.
Claims14
A method for repairing and/or optimizing a solar module having a sun-facing front and a sun-averted back, wherein a multiplicity of solar cells are encapsulated between the front and the sun-averted back, comprising the following steps:
- a) providing a solar module;
- b) energizing the solar module in a reverse direction by the application of an electric voltage;
- c) identifying a damaged region of the solar module based on the energization of the solar module in the reverse direction;
- d) after identifying the damaged region, energizing the solar module in the reverse direction by the application of the electric voltage to the solar module while simultaneously locally illuminating and scanning the identified damaged region of the solar module with a point light source, such that a current is induced in the solar module at the identified damaged region, the current having a current density of 200 A/cm2 to 20,000 A/cm2, thereby improving capacity of the solar module at the identified damaged region.
