Scientists in Germany have developed a new process for deposition of silicon dioxide layers during cell production. Without the need for high pressure, flammable gases, or vacuum conditions, the process could lead to cost reductions for cell manufacturers, provided it can be developed and applied in a large-scale production setting.
Bids are invited from Indian manufacturers to supply four-/five-busbar multi-crystalline silicon solar cells rated for 4.5W peak output. Bidding closes on March 15.
India’s Ministry of New and Renewable Energy is funding the research to develop high-efficiency crystalline silicon solar cells, including those with passivated emitter and rear contact structure, and perovskites.
Manufacturers have until December 22 to bid for supplying 200,000 four-/five-busbar solar cells rated for a power output of 4.5 watts.
