A leading solar cell manufacturer in Asia has placed its first order with Meyer Burger, via its subsidiary, Roth & Rau for its ‘Heterojunction’ technology that combines amorphous silicon thin-film layers to both sides of monocrystalline silicon wafers.
The company said that the order, which includes its ‘HELiA’ PECVD and ‘HELiA’ PVD coating systems would be delivered in the first quarter of 2014 and was worth around CHF14 million (US$15.7 million).
The Heterojunction production line is capable of producing 2,400 W/h and is capable of producing cells with conversion efficiencies higher than 21%.
The Roth & Rau HELiA PECVD system is capable of depositing uniform thin layers of intrinsic and doped a-Si:H onto textured Si-wafer surfaces. The PVD system provides for front and backside deposition without the need to flip the wafer, increasing throughput.
The contacting of heterojunction cells is carried out on both sides by means of transparent, conductive oxide layers (TCO), deposited using the PVD HELiA PVD sputtering unit in a continuous process. The HELiA PVD sputtering unit can deposit different contact layers sequentially and is designed to have the same throughput as the PECVD system.
Meyer Burger has announced a fresh wave of new orders in the last week, including line upgrade orders as well as new technology buys that could be a the strongest indicator yet of both a recovery in equipment orders for the sector and the start of the next technology buy cycle for next-generation high-efficiency solar cells and modules.
