The recent process and future of perovskite solar cells materials
Perovskite solar cells (PSCs) provide attractive prospects for the photovoltaic industry, but the harsh preparation conditions and stability of perovskite materials are still the biggest obstacles to the industrialization of PSCs. This review paper compares the differences in composition and working principle between dye-sensitized …
Another major challenge for perovskite solar cells is the observation that current-voltage scans yield ambiguous efficiency values. The power conversion efficiency of a solar cell is usually determined by characterizing its current-voltage (IV) behavior under simulated solar illumination. In contrast to other solar cells, however, it has been observed that the IV-curves of perovskite solar cells show a hysteretic behavior: depending on scanning conditions – such as scan direction, sca…
