Effective surface passivation is crucial for improving the performance of crystalline silicon solar cells. Wang et al. develop a sulfurization strategy that reduces the interfacial states and induces a surface electrical field at the same time. The approach significantly enhances the hole selectivity and, thus, the performance of solar cells.

3.1 PERC solar cell. The PERC structure improves the ability of capturing light near the rear surface. It was first developed at the UNSW in 1983, and its design was published in a technical paper in 1989 with a then world record efficiency of 22.8%. The PERC technology is easier to fabricate and cost-effective.
As the first-generation solar cells, silicon solar cells, particularly crystalline silicon (c-Si) solar cells, still dominate the PV industry. However, many factors constrain their efficiency to a great extent, including the surface recombination of photogenerated electrons and holes and the reduction of light absorption on the front surface. To overcome these problems, many

Development of thin-film crystalline silicon solar cells is motivated by prospects for combining the stability and high efficiency of crystalline silicon solar cells with the low-cost production and automated, integral packaging (interconnection and module assembly) developed for displays and other thin-film solar cell technologies (see e.g., Figs. 1, 2, and 3).
We demonstrate through precise numerical simulations the possibility of flexible, thin-film solar cells, consisting of crystalline silicon, to achieve power conversion efficiency of 31%. Our
Here we will not elaborate on Si thin-film solar cells because they are out of the subject of high efficiency due to their lower efficiencies (~10 %) in comparison with c-Si wafer solar cells, although a record efficiency of 13.1 % has been achieved based on a "micromorph" tandem Si thin-film solar cell consisting of a top a-Si:H cell and a bottom microcrystalline Si (μc

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.
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.
Their failure modes are well understood and avoidable. Crystalline silicon modules have substantially higher efficiency than any non-concentrating modules on the market, which reduces the cost of the area-related balance of systems components. As the cost of the modules declines, the latter becomes a dominant cost of photovoltaic electricity.
There is very widespread and deep skill and infrastructure available in crystalline silicon technology, both within the photovoltaic and integrated circuit industries. Thousands of researchers and companies work in the area of crystalline silicon, feeding their capabilities into the manufacture of crystalline silicon materials, cells and modules.
Although there had been many earlier empirical analyses of silicon solar cell performance as well as the very general analysis in the radiative limit of Shockley and Queisser , the first modern analysis of silicon solar cells was given by Green and almost contemporaneously by Tiedje et al. .
