The Rb PDT facilitates defect passivation and a downshift of valence band maximum of the CIGSSe absorber, thereby improving power conversion efficiency and all device parameters. Due to these beneficial effects, a PCE of ~15% was obtained with an energy band gap of less than 1.1 eV, making it suitable for use as the bottom cell in a highly efficient tandem solar cell.

Using aqueous spray deposition in an air environment, highest PCE of 17.74 % was achieved for CdS/K-CIGSSe cell and that of 16.08 % for Zr4+-alloyed In2S3/K-CIGSSe cell with absorber band gap of less than 1.15 eV. Defect passivation through Zr4+-alloying in In2S3 and K-alloying in CIGSSe was found to enable significant improvement of PCE.

Renewable Energy

Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-greed) energy services. This course which deals with renewable energy, intends to prepare students for the challenges of designing, promoting and implementing renewable energy solutions within society's rapidly-changing energy-related industry cluster.
