Method of manufacturing absorption layers for solar energy systems and bath therefor |
摘要 |
Method for manufacturing solar absorption layers by electrodeposition of heavy metals, such as Ni and Co, from aqueous citrate solutions. The heavy metal citrates are produced by direct reaction of metal oxides or carbonates with citric acid. The electrolyte concentration is a maximum 5% and has a pH of between 8 and 11. The deposition process takes place at room temperature, bath voltages of 8 to 30 V, and current densities of 3 to 10 A/dm2. The layers produced by this method are well bonded black layers resistant to temperatures up to 700 DEG C.
