ABSTRACT
In order to shield perovskite solar cells (PSCs) from extrinsic degradation factors and ensure long-term stability, effective encapsulation technology is indispensable. Here, a facile process developed create glass–glass encapsulated semitransparent PSC using thermocompression bonding. From quantifying the interfacial adhesion energy considering power conversion efficiency of devices, it confirmed that bonding between layers formed on hole transport layer (HTL)/indium-doped tin oxide (ITO) glass an electron (ETL)/ITO can offer excellent lamination method. The PSCs fabricated through this have only buried interfaces both charge as surface transformed into bulk. leads larger grains smoother, denser interfaces, thereby not reducing defect trap density but also suppressing ion migration phase segregation under illumination. addition, laminated demonstrates enhanced stability against water. self-encapsulated with wide-band-gap (Eg ∼ 1.67 eV) demonstrate 17.24% maintain PCE > ∼90% in 85 °C shelf test for over 3000 h ∼95% AM 1.5 G, 1-sun illumination ambient atmosphere 600 h.
