D7.6 Update to D7.3, taking into account the latest advances in related fields

This report presents an overview of the current advancements in the field of photovoltaic (PV) technologies, with a special focus on perovskite-based systems. These materials have shown promising potential across a range of applications, including solar cells (PV), light-emitting diodes (LEDs), and detectors. In the realm of PV technologies, perovskite quantum dots (PeQDs) have been utilized to enhance the efficiency of solar cells, demonstrating notable records in performance. However, there are still some challenges, such as the need for ligand exchange processes and the choice of solvents, which need to be addressed for their wider implementation. For LEDs, perovskite materials have demonstrated high external quantum efficiency (EQE) for red, green, and near-infrared emissions. Still, blue-emission efficiencies remain a challenge due to their sensitivity to sub-bandgap defects and the instability of the necessary perovskite formulations. Perovskite detectors have also shown promise, particularly in the detection of high-energy radiation such as X-rays and gamma rays. Interestingly, the research in this field is contributing to the exploration of lead-free inorganic perovskite materials, expanding the possibilities for PSC.
Moving away from perovskite-based systems, we discuss the developments in other emerging PV technologies such as antimony chalcogenides, CZTSSe and BaZrS3 solar cells. These emerging technologies, while not as efficient as perovskite-based systems, provide valuable insights for further improving perovskite solar cell performance.
The document concludes with an outlook on the continuous advancements in thin-film technologies and highlights the importance of ongoing research to exceed the performance of single junction cells. Comparative meta-studies and technological "openness" are encouraged for strategic advantage in future PV research and provide valuable insights for decision-makers in the PV technology field, detailing the progress in perovskite-based systems and other emerging PV technologies.
