Abstract
Crystal Si photovoltaic accounted for 90% worldwide solar cell produced in 2007. Si will be the mainstream PV technology at least in next decade. This presentation will cover state-of-the-art crystalline silicon solar cell technology in the following areas: photovoltaic effect and solar cell characterization; solar Si material including solar Si feedstock, Si growth, and wafer sawing; Si solar cell and module structure, current standard cell and module production process; over 20% solar cell architectures and manufacture; and next generation high efficiency and low cost process including low cost Si, thinner wafer, and advanced light management. This workshop will encourage more people to work on PV so that we can accelerate our progress to reach the grid parity in the near future.
