| Abstract: | Photovoltaic technologies have been developing at a rapid speed nowadays. It is a renewable and environmentally friendly way to generate electricity. Among these highly-developed technologies, solar cells which are using ubiquitous solar power can absorb sunlight and convert it directly into electricity. Recently, a promising thin film technology has drawn considerable attention of researchers which is perovskite material due to its rapid growth in PCE over a very short time period, compared to other commercial PV technology. Moreover, perovskite solar cells (PSCs) show their huge potential in fabricating semi-transparent devices for tandem solar cell and building integrated photovoltaics (BIPV) applications. The main difficulty for a semi-transparent solar cell is that PCE intrinsically conflicts with device transparency. Therefore, many approaches are utilized to balance the trade-off between PCE and device transparency. In this thesis, blade coating is the key technology to do semitransparent solar cells at thin film. The cell parameters (i.e. Voc, Jsc, FF and PCE) used by blade coating is better than those used by spin coating at a thin film. By this way, it is simple and easy to do transparent solar cells. In the future, different thicknesses of perovskite absorbing layers were demonstrated to meet the corresponding requirements of tandem and BIPV applications. The semitransparent solar cells could also be the top cells of the tandem solar cells, including monolithic tandem and mechanically stacked tandem. Different methods with advantages and disadvantages solving above problems are compared in this report. Challenges (i.e. stability, environment-friendly and PCE) in the future are also represented. |
