Unlike an earlier "tandem" solar cell reported by members of the same team earlier this year — in which the two layers were physically stacked, but each had its own separate electrical connections — the new version has both layers connected together as a single device that needs only one control circuit.

摘要： Organic solar cells have received extensive attention due to their light weight, low cost, flexible. Because a single organic material absorbs only part of the sun light, laminated structure of solar cell, consisting of different absorption band gaps of organic material through the middle connecting layer, can both cover a larger part of the solar flux, and improve the circuit
The image on the left shows how a top-of-the-line monocrystalline solar cell works. It''s able to convert 17% to 18% of the sun''s light into electricity. The one on the right shows the Natcore stacked solar cell design, in which each layer is specifically engineered to absorb a different part of the natural light spectrum — something never before accomplished.
The present study evaluates the design and optimization of four-terminal (4-T) mechanically stacked and optically coupled configurations using SCAPS (solar cell capacitance simulator).

Photocurrent matching in conventional monolithic tandem solar cells is achieved by choosing semiconductors with complementary absorption spectra and by carefully adjusting the optical properties of the complete top and bottom stacks.

To assemble the two-terminal tandem perovskite/silicon solar cells, the optimized bifacial mesoscopic perovskite top cell has been mechanically stacked over a silicon
To tackle these hurdles, we present a mechanically stacked two-terminal perov-skite/silicon tandem solar cell, with the sub-cells independently fabricated, opti-mized, and subsequently coupled by contacting the back electrode of the meso-scopic perovskite top cell with the texturized and metalized front contact of the silicon bottom cell.
Mechanically stacked solar cells formed using adhesive bonding are proposed as a route to high-efficiency devices as they enable the combination of a wide range of materials and bandgaps.
In the run-up to disclose commercial products, both two-terminal and mechanically stacked four-terminal perovskite/silicon tandem solar cells have been recently reported to reach PCEs over 25%. 24–28 In principle,
To assemble the two-terminal tandem perovskite/silicon solar cells, the optimized bifacial mesoscopic perovskite top cell has been mechanically stacked over a silicon bottom cell by applying a pressure of around 1 kg cm −2 over the contact area between the two sub-cells (the perovskite solar cell substrate is a 2.5 × 2.5 cm 2 glass). Two
The current work showcases a comprehensive investigation into the development and optimization of four terminal tandem solar cell architectures, with a focus on exploring the most technologically viable impactful, and promising combinations of top cell materials (CdTe, GaAs, MAPbI 3, and MASnI 3) and bottom cell options (c-Si and CIGS).
To tackle these hurdles, we present a mechanically stacked two-terminal perovskite/silicon tandem solar cell, with the sub-cells independently fabricated, optimized, and subsequently coupled by contacting the back electrode of the mesoscopic perovskite top cell with the texturized and metalized front contact of the silicon bottom cell.
Both cells were kept at MPP for the whole duration of the test. As shown in Figure S9, both devices exhibited a similar degradation trend, with the T 80 (defined as the time the cell reaches 80% of its starting efficiency) being approximately 100 h for both the tandem solar cells and the single perovskite sub-cell.
To measure the electrical characteristics of the perovskite/Si tandem solar cells, the ITO back electrode of the perovskite solar cell was simply pressed on the metal grid of the Si solar cell, as schematically shown in Figure 1 C of the main text of the manuscript and in Figure S3 B. The two cells are aligned by means of a rack.
However, the solution processing of perovskite solar cells directly onto the textured front surface of high-efficiency amorphous/crystalline silicon heterojunction cells is the main bottleneck. Our simple two-terminal mechanical stacking of the sub-cells helps achieve highly performant PV devices.
Vice versa, by increasing the power from 0.40 to 0.67 W cm −2, the J-V characteristic of the bifacial mesoscopic perovskite solar cell exhibits an “S-shape.” This effect evidences damage of the PTAA/ITO interface, resulting in limited performance (PCE of 8.0%).
Different from the typical two-terminal tandem configurations, 24,29, 30, 31, 32 our “mechanical stacking approach” does not require a polished front surface of the silicon bottom cell to enable the subsequent solution processing of the perovskite top cells since the sub-cells are independently fabricated.
