AI Technical Summary

Technical Problem

Existing perovskite solar cell production equipment suffers from poor continuous production capacity, low production efficiency, uneven crystallization, and small particle size, mainly due to the mismatch between the annealing process and the preceding process time, as well as poor temperature uniformity.

Method used

Design a perovskite battery production system including multiple annealing furnaces, a circulating conveyor line, and a product conveyor line. Achieve continuous production by coordinating the duration of each process and ensure temperature uniformity through an improved air intake and exhaust system.

Benefits of technology

It improves the production efficiency and crystallization uniformity of perovskite solar cells, solves the problems of continuity and temperature inhomogeneity in production, and realizes an efficient crystallization annealing process.
