In order to further reduce the LCOE of PV, the conversion efficiency must increase beyond the practical limit of silicon technology (26% [1]). It is believed that tandem module technology, combining bottom c-Si cells with low-cost thin-film top cells, can overcome the silicon limit. Recently, bifacial glass/glass modules are gaining market share...

—4-terminal tandem technology is a straightforward approach to bring to the market perovskite/crystalline silicon tandem modules. However, dealing with 4 terminals poses a challenge at system level for practical deployment. We have produced large area 4-terminal perovskite/crystalline silicon tandem modules for a study of the performance of a 2...

In this work, we present an extensive characterization of plasma-assisted atomic-layer-deposited SnO2 layers, with the aim of identifying key material properties of SnO2 to serve as an efficient electron transport layer in perovskite solar cells (PSCs). Electrically resistive SnO2 films are fabricated at 50 °C, while a SnO2 film with a low...

The combination of a semi-transparent, wide band gap perovskite solar cell (ST PSC) with a crystalline silicon (c-Si) bottom cell in a tandem configuration is considered a promising approach to enhance solar cell efficiencies over the current single junction c-Si cell efficiencies. In this study, we use a simple model based on experimental EQEs...

In this paper we analyze and model perovskite/c-Si tandem cells with front and rear polySi passivated contacts on the bottom cell. A high-efficiency tandem approach will benefit from the high Voc potential of a c-Si bottom cell with front and rear polySi passivated contacts while the combination with a high band gap, semi-transparent, perovskite...

Digital printing of organic photovoltaic devices is presented as a viable option for the creation of increasingly complex device structures. Fully printed organic tandem junction devices were made that show a perfect summation of the open circuit voltages of the subcells. These results show the feasibility of complete digitally printed device...

Stabilities of ITO-containing and ITO-free organic solar cells were investigated under simulated AM 1.5G illumination and under concentrated natural sunlight. In both cases ITO-free devices exhibit high stability, while devices containing ITO show degradation of their photovoltaic performance. The accelerated degradation under concentrated...

Solar cells are generally optimised for operation under AM1.5 100 mW cm-2 conditions. This is also typically done for polymer solar cells. However, one of the entry markets for this emerging technology is portable electronics. For this market, the spectral shape and intensity of typical illumination conditions deviate considerably from the...

Tandem solar cells are the best approach to maximize the light harvesting and adjust the overall absorption of the cell to the solar irradiance spectrum. Usually, the front and back subcells are connected in series in two-terminal device (2T) designs which require a current matching between both subcells in order to avoid potential losses....

Polymer solar cells may be applied in portable electronic devices, where light intensity and spectral distribution of the illuminating source can be very different compared to outdoor applications. As the power output of solar cells depends on temperature, light intensity and spectrum, the design of the module must be optimized for the specific...
