  • Silver pastes for solar contacts?

    Silver pastes for solar contacts?

    50 companies make conductive silver pastes to form the electrical contacts in solar modules. This data-file tabulates the compositions of silver pastes based on patents, averaging 85% silver, 4% glass frit and 11% organic chemicals. Ten companies stood out, including a Korean small-cap specialist.

  • Silver demand: upside and substitution?

    Silver demand: upside and substitution?

    This data-file is a simple demand outlook for silver in the energy transition. Demand could rise 2.5x from 30kTpa to 85kTpa in 2050, driven by solar and electrification. Although in practice, we think a price spike will displace silver with copper.

  • Silver and gold: the economics?

    Silver and gold: the economics?

    This data-file captures the marginal cost of silver and gold production, at an integrated mining-refining operation. In our base case, a 10% IRR requires a silver price of $17/Oz and a gold price of $1,750/Oz, while the energy and CO2 intensities are an eye watering 100-150 tons/ton and 9,000 tons/ton, respectively. Numbers vary widely on…

  • Silver producers: leading companies?

    Silver producers: leading companies?

    Half of the world’s 28kTpa global silver market is controlled by 17 public companies, with silver output ranging from 0.1 – 2.0 kTpa, and co-producing gold, copper or other metals. This data-file is a screen of silver producers, in order to identify leading companies.ย

  • Solar contacts: silver bullet?

    Solar contacts: silver bullet?

    The front contacts in todayโ€™s solar cells are made of screen-printed silver, absorbing 11% of 2021โ€™s silver market. Silver can be substituted with copper, but manufacturing is c5x more costly. So we expect a silver spike, then a switch. This 16-page note explains our outlook, and who benefits?

  • Silver and gold: medal winners?

    Silver and gold: medal winners?

    Gold and silver are stores of value, especially in a world of persistently high inflation and low rates. Silver is also likely to be the main bottleneck for solar in the 2020s. Hence our 18-page note models the end-to-end mining and refining of these metals. We find very steep energy/CO2 curves, and fear supply shortages.…

  • Solar surface: silver thrifting?

    Solar surface: silver thrifting?

    Ramping new energies is creating bottlenecks in materials. But how much can material use be thrifted away? This is a case study of silver intensity in the solar industry, which halved in the past decade, and could halve again. Conclusions matter for solar companies, silver markets, other bottlenecks.

  • Cyanide production: the economics?

    Cyanide production: the economics?

    Hydrogen cyanide is a chemical intermediate, used for making perspex, nylon-6,6 and sodium cyanide, which in turn is a crucial chemical for extracting gold and silver from precious metal ores. Marginal costs are usually $1,500-1,650/ton and CO2 intensities are 2-3 tons/ton.

  • LONGi: technology review and solar innovations?

    LONGi: technology review and solar innovations?

    This data-file is our LONGi technology review, based on recent patent filings. The work helps us to de-risk increasingly efficient solar modules, a growing focus on perovskite-tandem cells, and low-cost solar modules, with simple manufacturing techniques that may ultimately displace bottlenecked silver from electrical contacts. Key conclusions in the data-file.

  • Model of losses in a solar cell: surface, emitter and shading?

    Model of losses in a solar cell: surface, emitter and shading?

    This data-file calculates the losses in a solar cell from first principles. Losses on the surface of the cell are typically c4%, due to contact resistance, emitter resistance and shading. Sensitivity analysis suggests there may be future potential to halve silver content in a solar cell from 20g/kW to 10g/kW without materially increasing the losses…
