  • Semiconductor physics: piรจce de resistance?

    Semiconductor physics: piรจce de resistance?

    Semiconductors underpin solar panels, electric vehicles and electronics. Hence this 20-page note aims to explain semiconductor physics from first principles: their conductivity and resistance, their use in devices, plus implications for materials value chains and the energy transition itself?

  • Perovskite solar: beyond silicon?

    Perovskite solar: beyond silicon?

    Will the next chapter of solarโ€™s ascent come from perovskite-tandem cells, followed by perovskite-on-perovskites? This 18-page report finds more momentum than we expected. There is potential for 30% cost deflation, new solar applications (in buildings/vehicles), and a disruption of PV silicon?

  • Electromagnetic energy: Planck, Shockley-Queisser, power beaming?

    Electromagnetic energy: Planck, Shockley-Queisser, power beaming?

    Electromagentic radiation is a form of energy, exemplified by light, infrared, ultraviolet, microwaves and radiowaves. What is the energy content of light? How much of it can be captured in a solar module? And what implications? We answer these questions by explaining the Planck Equation and Shockley-Queisser limit from first principles.

  • Silicon carbide: faster switching?

    Silicon carbide: faster switching?

    Silicon carbide power electronics will jolt the energy transition forwards, displacing silicon, and improving the efficiency of most new energies by 1-10 pp. Hence we wonder if this disruptor will surprise to the upside, quintupling by 2027. This 12-page note reviews the technology, advantages, challenges, and who benefits?

  • Global polysilicon production capacity?

    Global polysilicon production capacity?

    Polysilicon is a highly pure, crystalline silicon material, used predominantly for photovoltaic solar, and also for ‘chips’ in the electronics industry. Global polysilicon capacity is estimated to reach 1.65MTpa in 2023, and global polysilicon production surpasses 1MTpa in 2023. China now dominates the industry, approaching 90% of all global capacity.

  • Hillcrest: ZVS inverter breakthrough?

    Hillcrest: ZVS inverter breakthrough?

    Hillcrest Energy Technologies is developing an ultra-efficient SiC inverter, which has 30-70% lower switching losses, up to 15% lower system cost, weight, size, and thus interesting applications in electric vehicles. How does it work and can we de-risk the technology?

  • DC-DC power converters: efficiency calculations?

    DC-DC power converters: efficiency calculations?

    DC-DC power converters are used to alter the voltage in DC circuits, such as in wind turbines, solar MPPT, batteries and digital/computing devices. This data-file is a breakdown of DC-DC power converters’ electrical efficiency, which will typically be around 95%. Losses are higher at low loads. We think there will be upside for increasingly high-quality…
