| description | <p>Climate change and energy crisis are regarded as the two main global challenges threating the modern society. In this context, the development of photovoltaic solar cells has been placed on great expectations due to their clean and renewable energy features. As one representative among the emerging photovoltaic technologies, perovskite solar cells (PSCs) have made huge progress during the past decade. Pairing with another skyrocketing organic solar cells (OSCs), it is expected to further advance the device performance via realizing the monolithic perovskite-organic tandem solar cells (POTSCs), which will be presented in this thesis. </p>
<p>Firstly, the broad background and theory (Chapter 1 & 2) are introduced for general readers. Materials and Methods that used in this thesis are described in Chapter 3. As
the wide bandgap (WBG) perovskites are vital to the POTSCs, a geometric
manipulation strategy to optimize WBG PSCs is presented in Chapter 4. Next, a multifunctional buffer layer, ytterbium oxide, is reported in Chapter 5 to alleviate the stability issue and contributes to efficient and stable PSCs. Targetting on the interfacial losses, a surface treatment is performed on WBG perovskite surface. To pair with the WBG subcells, the narrow bandgap (NBG) subcells based on organic absorbers is prepared. Followed by the design of interconnecting layers (ICL), the monolithic POTSCs comprising WBG-ICL-NBG are fabricated, where optical simiulation is carried out to provide optimization guidance (Chapter 6). Finally, the summary and
hints for future studies are presented in Chapter 7.</p> |
