A planar formal carbon based perovskite solar cell with a hole transport layer can be manufactured at low temperatures at low costs, with enormous potential for large-scale manufacturing. In addition, two-dimensional perovskites have attracted widespread attention due to their high stability.
Zhang Putao et al. from Henan University reported a scalable and efficient fully printed large-area carbon based two-dimensional perovskite module by inserting a thin interface layer based on naphthalimide derivatives (CATNI) between tin oxide (IV) and perovskite layers. The results indicate that this is beneficial for the formation of interface contact, suppresses energy loss, and significantly improves the performance parameters of perovskite solar cells, especially their VOC value. The open circuit voltage significantly increased to 1.13 V, and the device efficiency value reached over 18%.
Research has found that by deploying this CATNI based interface layer, more effective carrier extraction can be achieved. This ultimately helps to enhance spectral response and improve the open circuit voltage of these carbon based fully printed devices. Finally, at a size of 5.0 × Manufacturing carbon perovskite solar modules on a 5.0 cm ITO glass substrate. These prepared components exhibit excellent photovoltaic performance, with a maximum efficiency value exceeding 14.6%.
