The compact TiO 2 layer of the mesoporous perovskite solar cells significantly reduced the carrier recombination and enhanced the conversion efficiency. The above significant properties of the compact TiO 2 implies its necessity for the perovskite solar cells which has been discussed.
Mesoporous perovskite solar cells were fabricated with and without a compact TiO 2 layer. The carrier recombination was efficiently reduced by the compact TiO 2 layer. The compact TiO 2 layer enhanced the carrier transportation and reduced the hysteresis. The perovskite solar cell with the compact TiO 2 showed a highest efficiency of 15.51%.
The significant enhancement is ascribed to its excellent morphology, high conductivity and optical properties, fast charge transfer, and large recombination resistance. Thus, a power conversion efficiency (PCE) of 17.03% has been achieved for the solar cells based on c-TBOT.
The solar cells are connected with needle probes and the electrical measurements are made with a Keithley 2601 SMU. The assembly is also equipped with a TEC 2510 temperature controller. A reference cell is used to calibrate the lamp. One-sun measurements were carried out on cells ranging from 12.25 mm to 0.01 mm.
Micro-Concentrator photovoltaics modules promise to overcome the limitations of CPV such as thermal losses or resistive losses. Miniaturization involves new challenges in the field of cells fabrication, particularly the management of perimeter recombinations.
Perovskite solar cells (PSCs) have attracted tremendous attentions due to its high performance and rapid efficiency promotion. Compact layer plays a crucial role in transferring electrons and blocking charge recombination between the perovskite layer and fluorine-doped tin oxide (FTO) in PSCs.
