1. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells
Sammanfattning : Emerging solar energy conversion and energy storage technologies play a vital role in solving the present energy crisis and achieving carbon net zero. Currently, they are limited by the use of inefficient, unstable and expensive charge transport materials. LÄS MER
2. Light Trapping and Alternative Electrodes for Organic Photovoltaic Devices
Sammanfattning : Organic materials, such as conjugated polymers, have emerged as a promising alternative for the production of inexpensive and flexible photovoltaic cells. As conjugated polymers are soluble, liquid based printing techniques enable production on large scale to a price much lower than that for inorganic based solar cells. LÄS MER
3. III-V Nanowire Solar Cells: Growth and Characterization
Sammanfattning : To mitigate dangerous climate change, a transition to a new and sustainable energy system is needed. In this system, solar energy will need to be a key player. Prices of electricity made from solar cells have declined rapidly over the recent decades, making solar energy competitive in more markets. LÄS MER
4. Modelling and Degradation Characteristics of Thin-film CIGS Solar Cells
Sammanfattning : Thin-film solar cells based around the absorber material CuIn1-xGaxSe2 (CIGS) are studied with respect to their stability characteristics, and different ways of modelling device operation are investigated. Two ways of modelling spatial inhomogeneities are detailed, one fully numerical and one hybrid model. LÄS MER
5. Recycling of selenium from CIGS solar cell materials
Sammanfattning : Today the importance of solar cells as a power source is growing due to the environmental advantages compared to fossil fuels. One of the most promising new solar cell materials, resulting in high efficiency solar cells, is copper indium gallium selenide (CIGS). LÄS MER
