The best laboratory and commercial silicon solar cells currently reach 24-25% efficiency under non-concentrated sunlight, which is about 85% of the theoretical limit. The main commercial motivation for developing higher cell efficiency is reductions in the area-related costs.
A team from the Australian National University (ANU) in Canberra announced they had reached the first 30, achieving a 30.3% efficiency. The perovskite and silicon tandem solar cell have ultra-high efficiency, while also enhancing the operational stability of the solar cells, said the team.
The theoretical limiting efficiency of the crystalline silicon solar cell under non-concentrating sunlight is about 29% . This is not far below the theoretical limit for any single junction solar cell.
Silicon remains the material of choice for photovoltaics because of its abundance, non-toxicity, high and stable cell efficiencies, the maturity of production infrastructure and the deep and widespread level of skill available in relation to silicon devices.
Improving solar cell efficiencies A high-performance silicon solar cell has excellent optics (low reflection, low parasitic absorption from free carriers and metal contacts, excellent light trapping); low levels of avoidable recombination (at surfaces, in the junction, in the bulk, and around the cell perimeter); and low resistive losses.
A research team at the Australian National University have claimed an efficiency of 30.3% for a tandem solar cell made by mechanically stacking a perovskite cell and a silicon cell. The achievement meets the first of three 2030 “stretch goals” set by the Australian government.
