Abstract:
>Magister Scientiae - MSc<br>TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have significant electron trap-sites as a result of the large density of oxygen vacancies present in nano-sized TiO2. These trap-sites cause electron-hole recombination and ultimately lower photon-to-current conversion efficiency of the underlying cell during operation. Doping the TiO2 lattice with low atomic number elements such as nitrogen is a proven method to overcoming the char

碩士<br>中原大學<br>電子工程研究所<br>105<br>In this study, the electron transport layers (ETLs) effect on perovskite solar cells was discussed. First, we used sol-gel process ZnO as ETLs in the perovskite solar cells, and then we used ZnO/Al-doped ZnO (AZO) as ETLs in the perovskite solar cells. The power conversion efficiency (PCE) of perovskite solar cells were increased from 12.41% to 14.67% with open-circuit voltage (Voc) of 1.09V, short-circuit current density (Jsc) of 19.41 mA/cm2, and fill factor (FF) of 68.99% by using the AZO thin film.

Compared with the current silicon-based solar cells, solar cells with polymer materials have the advantages of simple process and large-area production and those with quantum dot (QD) materials have low cost and easy to adjust their band gaps. Therefore, solar cells with polymers and QDs as light absorbing materials are important advanced research topic in solar cells. It is expected to become the latest generation of green e

The oxetane groups on PCBOD will anchor the hydroxyl groups on the TiO2 surface in helps of photoacid generator and also form multi-layer cross-linked PCBOD (C-PCBOD). From the results of EI
