The invention relates to a perovskite solar cell structure which sequentially comprises a cathode transparent conducting substrate, an electron transport layer, a perovskite layer, a hole transport layer and a metal anode. The electron transport layer is a titanium dioxide-coated metal particle core-...
The fabricated device structure was glass or PET/SWCNTs/PEDOT:PSS/CH3NH3PbI3/PC61BM/Al, in which SWCNT film acted as an electron blocking layer. The transparent conducting SWCNT electrode-based planar heterojunction perovskite solar cell achieved a PCE of 6.32%, which is 70% of an ITO-based...

Structure of a perovskite solar cell | Source:Li, S. et al. Perovskite solar cell manufacturers place a perovskite absorber layer between ETL and HTL, with both of these layers being sandwiched between electrodes, and the transparent layer is then covered with glass. The most widely used method...

which creates an atomic-scale double band structure. Under light, the excited electrons could relax from one component (smaller bandgap region) to another component (larger bandgap region) before equilibrating to alter the fermi levels in the superlattice solar cell. This contributes to a higher op...
Perovskite solar cells (PSCs) are photovoltaic (PV) devices containing a light-absorbing layer that has the general formula AMX3,[1] and a crystal structure similar to the mineral perovskite (CaTiO3). The advantageous electronic and optical properties of perovskites have contributed to impressive ...
