The demands of sustainable energy sources and depletion of conventional energy sources have accelerated the quest for attaining nontoxic and low‐cost organic solar cells (OSCs). The intrinsic characteristics of organic semiconductor materials such as light weight, mechanical stability, tailorable bandgaps, and ease of solution processability on a large area with flexible devices provide new dimensions to the device engineers toward sustainable electronic technologies. The past two decades have witnessed an inspiring breakthrough of device efficiency by developing multijunction architectures. The significance of organic tandem solar cells (OTSCs) does not only elevate the efficiencies but also considerably reduces the absorption losses. Herein, the recent developments in OTSCs, starting from designing rules for OTSCs, followed by implementation of the interconnecting layer (ICL) structure, and issues regarding processing, light management, and engaging photoactive materials for constructing OTSCs, are comprehensively described. Finally, the conclusion and outlook for OTSCs are provided.

“…[4][5][6] However, compared with the traditional crystalline silicon and the emerging perov skite solar cells, the PCE of OSCs are still limited by insufficient light absorption and the thermalization photon energy losses. [7] To overcome the limitation of single junction OSCs, the idea of the tandem structured device, which could enhance and expand the sunlight harvesting by two or more subcells with complementary absorp tion spectra, has attracted considerable attention. [8] In seriesconnected organic tandem solar cells (OTSCs), the front sub cell requires the widebandgap materials to harvest the high energy photo ns for a high opencircuit voltage (V oc ), while the rear subcell needs the narrowbandgap mate rials to absorb the low energy photons for balanced shortcircuit current density (J sc ).…”

Organic tandem solar cells (OTSCs) with the merits of overcoming the S‐Q limit of single‐junction, enhancing and expanding the sunlight harvesting, and minimizing the thermalization energy loss, provide a practical strategy to break through the power conversion efficiency (PCE). However, it is still challenge to realize the multilayered structure by all‐solution processing, especially shortage of interconnection layer (ICL), which physically and electronically connects front and rear subcells to accomplish the complicated tandem structure. Herein, all‐solution‐processed ICL of modified poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (m‐PEDOT) and titanium (diisopropoxide) bis(2,4‐pentanedionate) (TIPD) is invented for constructing inverted OTSCs, and by systematically managing the light and carriers within the stacked multilayers, highly efficient OTSCs are demonstrated. Compared with the traditional ICLs, it avoids the complicated vacuum evaporation and synthesis processes, guaranteeing low cost and high reproducibility. Furthermore, m‐PEDOT/TIPD ICL demonstrates excellent solvent resistance, high transmittance, and good conductivity. To enhance the light harvesting, absorption complementary donors and acceptors are selected as photoactive materials in front and rear subcells, and the transfer matrix formalism optical modeling is introduced to achieve the balanced short‐circuit current density of each subcell in OTSCs. By systematic device optimizations, the best PCE of 15.26% is achieved, among the best results reported for OTSCs.
