This course will deliver the students the current technologies of using solar energy and the its potentials, including photovoltaic and solar-thermal. In the photovoltaic part, this course mainly includes technology and processes of single crystalline silicon solar cell, silicon-based thin film solar cells, CdTe solar cells, CIGS solar cells, organic solar cells, DSSC, novel compound quantum dots solar cells, inverter and grid, etc. In the solar-thermal part, this course introduces the heat collecting and converting technique from solar light, the key materials and devices structures involved. In addition, basic concepts on process control are also presented in this course, such as Cpk, 6Ω.
