Here, the robustness of perovskite-silicon tandem solar cells to reverse bias electrical degradation down to −40 V is investigated. The two-terminal tandem configuration, with the perovskite coupled to silicon, can improve the solar cell resistance to severe negative voltages when the tandem device is properly designed.
It will be important to give evidence that the lifespan of PSCs can match the 25–40 years operating time demanded of solar modules. This calls for the implementation of accelerated aging tests capable of projecting the stability of PSCs under realistic outdoor conditions.
3Sun s.r.l. is a company with interest in the production and commercialization of photovoltaic modules. Abstract The reverse bias stability is a key concern for the commercialization and reliability of halide perovskite photovoltaics. Here, the robustness of perovskite-silicon tandem solar cells to r...
These results indicate that monolithic perovskite/Si tandem solar cells, in addition to many well-known benefits such as higher PCE and well-developed Si manufacturing, have an additional advantage in withstanding reverse-bias stress and show superior stability under partial shading conditions.
Under reverse bias conditions, perovskite solar cells have been shown to degrade quickly due to processes that have so far remained elusive. Here, we combine optical, microstructural, and elec. characterization to address the mechanisms governing perovskite solar cell degrdn. under reverse bias.
However, we highlighted that the tandem solar cells' resistance to the reverse bias is not universal but depends on the electrical and optical design of the device. In fact, the protection from silicon is effective if the bottom cell features a breakdown voltage in the range of −40 V along with a high shunt resistance.
