Material quality, process technologies, and solar cell architectures have improved significantly in recent past decades, and solar cell efficiencies are now approaching 27%, thus close to the theoretical limit. However, challenges remain in several aspects, such as increasing the production yield, stability, reliability, cost, and sustainability.
Silicon-based solar cells are still dominating the commercial market share and continue to play a crucial role in the solar energy landscape. Photovoltaic (PV) installations have increased exponentially and continue to increase. The compound annual growth rate (CAGR) of cumulative PV installations was 30% between 2011 and 2021 .
The reasons for silicon’s popularity within the PV market are that silicon is available and abundant, and thus relatively cheap. Silicon-based solar cells can either be monocrystalline or multicrystalline, depending on the presence of one or multiple grains in the microstructure.
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. Additionally, the tandem solar cell should be designed to prevent perovskite-limiting conditions in terms of current mismatch.
