AI Technical Summary

Technical Problem

The xenon lamp spectrum of existing photonic sintering equipment covers the ultraviolet to near-infrared range, which causes perovskite solar cells to be damaged by visible and ultraviolet light during low-temperature sintering. Meanwhile, infrared light sources have poor large-area uniformity, short lifespan, and high cost.

Method used

A selective light filtering device is used, including a filter optical component, a circulating filter liquid and a cooling device, to filter out visible light and ultraviolet light, allowing only infrared light to pass through. Selective light filtering sintering is performed using a xenon lamp light source.

Benefits of technology

This technology enables low-temperature sintering of perovskite solar cells without damage, extends the uniformity and lifespan of the infrared light source, and reduces material costs.
