Crystalline Solar Cells
Sunlight is converted into electrical energy in solar cells, the core component of photovoltaic systems. Manufacturing these systems involves a wide range of production steps — from silicon extraction to module production. To manufacture these crystalline solar cells, Manz AG concentrates on the third step in the value creation chain: The process from wafer to cell.
Solar producers can beat the constant cost pressure in the solar industry only by increasing the solar cells’ efficiency while lowering manufacturing costs. These requirements place huge demands for precision, performance and output on the production equipment.
For production of next-generation crystalline solar cells — the high-efficiency PERC cells (passivated emitter rear cells) — Manz offers trailblazing production technology for nearly every step of the process. The fully integrated, optimally coordinated systems achieve maximum efficiency at the lowest cost.
From the wafer tester and the wet chemical processes to texturing, PSG etching and edge insulation, from vacuum coating systems to bilateral passivization of the solar cell, from laser systems to the creation of a selective emitter and laser ablation, from high-precision printing equipment to the cell tester — Manz customers receive all process equipment, including integrated automation solutions and measurement technology, from just one source.
