Solar Energy Research Projects
Taking advantage of Qatar’s abundant solar energy is an obvious choice in diversifying the country’s energy resources. Because of the specific climate conditions, the most effective way to utilize the solar energy is through Photovoltaics. Our portfolio includes:
Silicon-based Photovoltaic technologies: Developing crystal growth capabilities to produce silicon ingots that are suitable for fabricating high performance solar cells of high performance; producing monolike silicon wafers with low levels of impurity and dislocations and few millisecond carrier lifetime; design and fabrication of silicon heterojuction solar cells of high performance and lower cost.
Thin-film Photovoltaics Technologies (TF-PV): Our project follows the roadmap towards thinner, cheaper and more efficient devices, to accelerate the decrease in the cost-efficiency ratio for thin film PV modules. We focus on design, concept and device options, which are related to the ability to widely tune the physical properties and the surface and interface.
Organo-metallic Photovoltaic Perovskites: Despite being recently developed, the perovskite based solar cells have high efficiencies reaching 20%. We are developing perovskite based solar cells using different materials and architectures for higher stability, and device efficiency comparable to published world records. Emphasis will be on the selection of new electron transport material (ETM) and hole transport material (HTM) as well as Pb-free based perovskites deposited with cost effective methods.
Photovoltaics Modules Performance and Reliability in the Desert Environment: High temperature and humidity, UV radiation, atmospheric salinity and dust accumulation have a significant impact on the performance of PV modules and their life span.
We address these challenges by: Comparing the performance and reliability of different PV module technologies; evaluating the impact of temperature, dust accumulation and solar spectrum on PV module performance and reliability and development of technologies to mitigate such impact; establishing indoor laboratory capabilities for accelerating environmental testing of PV modules; modelling annual PV modules energy output in different climatic conditions; and building capability in Qatar to support PV deployment at utility scale.
