“…Several patterning approaches have so far been demonstrated successfully for PSMs, [23,29,30]. However, laser patterning is the preferred choice for industrial exploitation of this technology since it has been optimized for second generation technologies already [31] and this technique provides for the best trade-off between manufacturability and minimized dead areas (DAs).…”

“…In this way, it is possible to selectively remove the perovskite and HTM from the interconnection regions, without damaging the TCO and leaving the latter surface free to receive the evaporated counter-electrode of the next cell (in a series connection), as shown in Fig.1, realizing a low-resistance vertical contact. [29,37,38] Razza et al [24] reported the first PSM to have an AA = 100 cm 2 , that showed a PCE = 4.3% and an AR = 73%, adopting P3HT as HTM. The realization of this large PSM required the adoption of an airflow-assisted blade coating technique to deposit the active layers while the laser patterning was based on the use of a CO2 laser (λ = 10600 nm, Pulse duration: 53.4 µs) for a rapid prototyping.…”

“…Afterwards, Moon et al reported the first application of a full P1-P2-P3 laser patterning procedure for a PSM, obtaining a PCE = 6.6% on an AA = 5 cm 2 with an AR = 84%. [29] In this case, the P1 was realized on a 20-nm-thick c-TiO2 deposited over an FTO covered glass substrate, using a λ = 355 nm, nanosecond pulse laser to insulate the c-TiO2/FTO stack, realizing 74 μm wide lines. The P2 scan, realized with a Newport Explorer, λ = 532 nm, nanosecond pulse laser, was applied to remove 20-nm-c-TiO2/ncTiO2/CH3NH3PbI3/Spiro-OMeTAD, realizing a 180 µm wide scribe.…”

Small area hybrid organometal halide perovskite\ud based solar cells reached performances comparable to the multicrystalline\ud silicon wafer cells. However, industrial applications\ud require the scaling-up of devices to module-size. Here, we report\ud the first fully laser-processed large area (14.5 cm2) perovskite solar\ud module with an aperture ratio of 95% and a power conversion\ud efficiency of 9.3%. To obtain this result, we carried out thorough\ud analyses and optimization of three laser processing steps required\ud to realize the serial interconnection of various cells. By analyzing\ud the statistics of the fabricated modules, we show that the error\ud committed over the projected interconnection dimensions is sufficiently\ud lowto permit even higher aperture ratios without additional\ud efforts

“…11 Laser patterning is able to reduce the dead areas in perovskite based modules, minimizing such areas used for contacts. 53 Patterning can be performed in three sequential steps (P1-P2-P3) used to create the necessary spacing/isolation for the electrodes of adjacent sub cells (P1-P3) and to isolate clean the contact areas (P3). Figure 4(b) shows the scribes and their role in cell connections.…”

Research Update: Large-area deposition, coating, printing, and processing techniques for the upscaling of perovskite solar cell technology

To bring perovskite solar cells to the industrial world, performance must be maintained at the photovoltaic module scale. Here we present large-area manufacturing and processing options applicable to large-area cells and modules. Printing and coating techniques, such as blade coating, slot-die coating, spray coating, screen printing, inkjet printing, and gravure printing (as alternatives to spin coating), as well as vacuum or vapor based deposition and laser patterning techniques are being developed for an effective scale-up of the technology. The latter also enables the manufacture of solar modules on flexible substrates, an option beneficial for many applications and for roll-to-roll production.

“…[19][20][21][22][23][24] However, there is a lack of data on the tracking of the maximum power output for perovskite solar modules, which has proven to be essential, considering the hysteresis of perovskite solar cells. 25 Moreover, there are still limited reports of perovskite solar modules with high aperture area PCEs due to the reported low geometrical fill factors (the ratio of the active area to the aperture http://eprints.lincoln.ac.uk/22663/1/c5ee03703d 3/12 area).…”

We report on a perovskite solar module with an aperture area of 4 cm 2 and geometrical fill factor of 91%. The module exhibits an aperture area power conversion efficiency (PCE) of 13.6% from a current-voltage scan and 12.6% after 5 min of maximum power point tracking. High PCE originates in pinhole free perovskite films made with a precursor combination of Pb(CH 3 CO 2 ) 2 ·3H 2 O, PbCl 2 , and CH 3 NH 3 I. Broader contextRecently, significant progress has been made in organometallic halide perovskite solar cell research, boosting the record certified power conversion efficiency (PCE) up to 20.1%.
