What are the specific ways to improve the efficiency of photovoltaic modules?

(1) Improve the original preparation process and develop new processes to increase the output of silicon raw materialsAt present, there are reports on some new process methods: vapor to liquid deposition (VLD) and molten silicon refinement. In the VLD method, trichlorosilane (SiHC3) and hydrogen (H2) are injected together into a graphite tube at 1500°C to […]
