1. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell
University essay from KTH/Tillämpad fysikAbstract : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

2. Modulation of the optical properties of quantum dots by surface acoustic waves
University essay from KTH/Tillämpad fysikAbstract : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. READ MORE

5. Properties of III-V/Si heterojunction fabricated by HVPE
University essay from KTH/Tillämpad fysikAbstract : Silicon is a promising material and is used for a wide range of applications in the electronics industry because of the high quality surface passivation given by the native oxide layer SiO2e. However, Si is not an ideal candidate for optoelectronic applications due to its indirect bandgap of 1. READ MORE
