16. Organic Hole-Transport Materials for Perovskite Solar Cells
Sammanfattning : Research on perovskite solar cells (PSCs) has undergone dramatic development since the first cells were reported in 2009, and the past decade has witnessed a significant breakthrough on their power conversion efficiencies (PCEs) from 3.8% to 25%. LÄS MER
17. The Multiple Faces of Interfaces : Electron microscopy analysis of CuInSe2 thin-film solar cells
Sammanfattning : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. LÄS MER
18. Development of Concentrating Photovoltaic-Thermal Solar Collectors
Sammanfattning : Fossil fuels have greatly improved human living standards and saved countless lives. However, today, their continued use threatens human survival, as CO2 levels rise at an unprecedented pace to levels never seen during human existenceon earth. LÄS MER
19. Studies of Semiconductors Modified with Nanoscale Light Absorbers for Solar Cell Application
Sammanfattning : Recently, materials such as hole conductors (CuI, CuSCN) and light absorbers (Ru-complexes, CuInS2) have been actively investigated for application in nanocrystalline solar cells. In this thesis combinations of these materials have been studied. LÄS MER
20. The Study of II-VI Semiconductor Nanocrystals Sensitized Solar Cells
Sammanfattning : Semiconductor nanocrystals, also referred to as quantum dots (QDs), have been the focus of great scientific and technological efforts in solar cells, as a result of their advantages of low-cost, photostability, high molar extinction coefficients and size-dependent optical properties. Due to the multi-electron generation effect, the theoretically maximum efficiency of quantum dots-sensitized solar cells (QDSCs) is as high as 44%, which is much higher than that of dye-sensitized solar cells (DSCs).
