Tandem cells are effectively a stack of different solar cells on top of each other. By arranging them like this, we can capture more energy from the sun.
Adding more devices allows for each device to be optimized to a narrower spectrum giving a higher overall efficiency. Tandem solar cells can either be individual cells or connected in series. Series connected cells are simpler to fabricate but the current is the same though each cell so this contrains the band gaps that can be used.
Schematic of simple configurations for tandem solar cells: 4T stacked, 4T with spectral splitting, 2T, and 3T Two terminal (2T) tandem devices consist of multiple semiconductor junctions that are both optically and electrically connected in series.
The first report on two-terminal organic tandem solar cell was by Hiramoto et al. Two identical sub-cells were connected by a very thin and incomplete Au layer between the acceptor of the front cell and the donor of the rear cell [ 27 ], the efficiency improvement is minor or even negative in most of the cases due to the competing absorption.
A consortium aimed specifically at tandem solar cell development with broad participation across industry, national labs, and academic research teams will help to make tandems the same progress as other PV technologies. Bankability must be evaluated to determine the most economically sustainable path to increase the PV market share of tandems.
Finally, the 2T tandem device achieved a certified 25.7% PCE with a Voc of 1.78 V, a Jsc of 19.3 mA/cm 2 and an FF of 75%. 56 The high Jsc of the tandem solar cell can be ascribed to not only the reduced optical loss, but also the relatively low bandgap (1.68 eV) of perovskite used in this study.
