(a) Tandem solar cell configurations can be mapped onto four broad categories depending on electrical or optical constraints. Electrically, the subcells of a Bifacial tandem are connected in series; however, optically, the direct illumination passes through the cells sequentially, but the albedo back-reflection provides some optical independence.
Tandem (double junction) or multi-junction solar cells have been studied intensively over the years and are now a reliable technology, e.g. for space solar cells. The concept of tandem solar cells is to stack different absorber layers on top of each other so that each layer sequentially absorbs light close to its bandgap. Thus, the sunlight
Up to now, multijunction cell design is the only successful way demonstrated to overcome the Shockley–Quiesser limit for single solar cells. Perovskite materials have been attracting ever-increasing attention owing to their large absorption coefficient, tunable bandgap, low cost, and easy fabrication process.
Multi-junction tandem solar cells involve the stacking of solar cells with different bandgaps (highest on the sun-facing side) allowing each cell to absorb different parts of the solar spectrum more efficiently, minimizing sub-bandgap and thermalization losses. Figures 1 (a) and 1 (b) illustrate two configurations for double-junction tandem cells.
Producing a tandem cell is not an easy task, largely due to the thinness of the materials and the difficulties extracting the current between the layers. The easy solution is to use two mechanically separate thin film solar cells and then wire them together separately outside the cell.
This has become a promising technology for next-generation, low-cost, high-efficiency photovoltaics including multi-junction tandem cell concepts. Double-junction tandem cells have much higher efficiency limits of 45%, beyond the Shockley–Queisser limits for a single-junction solar cell.
The subcells of a tandem solar device can be considered as a pair of series-connected diodes. While analyzing the performance of tandem devices, the TC and BC are simulated separately to obtained current matching points. Afterward, the J–V characteristics of the tandem device are determined by treating them as an equivalent series connection.
(Fig. 7d–f). Furthermore, the best stability of triple junction all-perovskite solar cells is currently 420 h, retaining 80% of their initial efficiency under illuminating and room temperature conditions from the literature. Hence, this triple junction field has promising potential for development of highly efficient and stable devices. 33–37
Tandem fabrication techniques have been used to improve the performance of existing designs. In particular, the technique can be applied to lower cost thin-film solar cells using amorphous silicon, as opposed to conventional crystalline silicon, to produce a cell with about 10% efficiency that is lightweight and flexible.
