Photovoltaic panel laser slotting process

How does laser processing improve the performance of perovskite solar cells?

Laser processing enhances the performance and reproducibility of perovskite solar cells by fine-tuning the surface morphology and micro-nano structure of the electron transport layer.

Why is laser technology important for solar energy production?

Solar energy is indispensable to tomorrow´s energy mix. To ensure photovoltaic systems are able to compete with conventional fossil fuels, production costs of PV modules must be reduced and the efficiency of solar cells increased. laser technology plays a key role in the economical industrial-scale production of high-quality solar cells.

How do thin film solar cells work?

In the case of conventional silicon solar cells, a thin conductive layer of metal is applied for contacting the doped silicon. In modern organic thin-film solar cells, not only contacting, but also semiconducting layers are applied to a transparent film.

How are silicon solar cells processed?

In order to achieve this in silicon solar cells, their surfaces are processed by means of laser radiation and plasma etching. Processing with laser radiation enables a defined periodic microscale structuring of the surface, which facilitates the absorption of the most energy-intensive part of the solar spectrum.
