Photoelectrochemical Cell Engineering for Solar Energy Conversion
Solar energy is the most abundant energy source, harnessing solar energy holds the solution to the challenge of increasing global energy demand and reducing our dependence on fossil fuels. Photovoltaics which directly convert solar energy into electricity ...
EPFL2023Chemical Trend of Nonradiative Recombination in Cu(In,Ga)Se2 Alloys
Nonradiative recombination in Cu(In,Ga)Se2 (CIGS) solar cells has long been attributed to the antisite defects MCu (M = In, Ga), but the underlying mechanism is still elusive. Using rigorous first-principles calculations, we demonstrate that the antisites ...
AMER PHYSICAL SOC2023Contact Design for Silicon Heterojunction Solar Cells
Today more than ever the world needs clean energy sources and thus a fast deployment and scaling up of the photovoltaic industry. In this context improving solar cell efficiency plays a major role. In order to achieve the maximum single junction efficiency ...
EPFL2022Modeling and assessment of high-temperature photo-electrochemical devices
In this thesis, the feasibility and performance of photo-driven electrochemical (PEC) devices working at elevated temperatures (T>700 K) is investigated and modeled. In such high-temperature PEC devices, a part of the solar spectrum is used for generating ...
EPFL2022Novel Interfacial Characterization and Surface Engineering in Semiconductor Electrodes for Optimized Solar Fuel Production
Harvesting sunlight, the ultimate renewable power source, in a cost-effective way has been long recognized as a necessary route to meet the global energy challenges. Solar energy can be transformed into electricity by means of photovoltaic devices to suppl ...
EPFL2021Characterisation of Silicon Heterojunction Solar Cells Beyond Standard Test Conditions
The global photovoltaic market is mostly dominated by solar cells based on crystalline silicon (c-Si), which are covering 95% of the market. This thesis concerns silicon heterojunction (SHJ), a high-efficiency technology with a 2% market share in 2018, but ...
EPFL2020Optoelectronic Properties of Layered Perovskite Solar Cells
Mohammad Khaja Nazeeruddin, Sanghyun Paek, Yonghui Lee, Kyung Taek Cho
Herein, the optoelectronic properties of interface-engineered perovskite 2D|3D-heterojunction structure solar cells are reported. The reciprocity theorem is applied to determine the maximum open-circuit voltage (V-oc) the device can deliver under solar ill ...
2019Silicon Photonic Broadband Suspended Directional Coupler
