Overview

Chinese solar giant JinkoSolar has set a new world record for perovskite-silicon tandem solar cell efficiency, achieving 34.82%. This SIMIT-certified breakthrough surpasses their previous record and positions the technology as a core component for next-generation solar, promising significant strides in renewable energy production and cost reduction, and accelerating global energy transition.

In Depth

Background

Perovskite-silicon tandem solar cells are considered a prime candidate for next-generation photovoltaic technology, as their theoretical efficiency limit significantly exceeds that of standalone silicon (approx. 29%) or perovskite (approx. 27-28%) cells. A key advantage of this technology is its compatibility with existing silicon solar cell manufacturing infrastructure, which could facilitate a relatively smooth transition to commercialization. Proactive record-breaking by leading manufacturers like JinkoSolar accelerates the entire industry’s technological development and moves perovskite technology closer to practical application. High efficiency is paramount for maximizing electricity generation per unit area and shortening the payback period for solar power systems.

Key Findings

JinkoSolar, a leading Chinese solar manufacturer, has achieved a new world record power conversion efficiency of 34.82% for its perovskite-silicon tandem solar cell, surpassing its previous benchmark. This remarkable achievement has been rigorously certified by the Shanghai Institute of Microsatellite Engineering Technology (SIMIT) of the Chinese Academy of Sciences, solidifying the company’s technological leadership.

Technical Details

The 34.82% efficiency was realized through a tandem structure, where the perovskite top cell efficiently absorbs short-wavelength light, and the underlying silicon bottom cell converts the transmitted longer-wavelength photons. This architectural design enables a broader and more efficient utilization of the solar spectrum compared to single-junction cells. JinkoSolar successfully optimized charge transport and minimized recombination losses between the perovskite and silicon layers by employing proprietary interface treatment techniques and advanced material designs. SIMIT’s independent certification validates the credibility of this efficiency record. This continuous improvement, following their previous record of 34.76%, underscores JinkoSolar’s commitment to relentless innovation in this field.

Strategic Significance and Outlook

JinkoSolar positions this 34.82% record as a crucial milestone for the commercialization of its next-generation solar cell products. The company aims to mass-produce and bring this technology to market within the next few years. If these high-efficiency modules become commercially available at scale, they are expected to further reduce the Levelized Cost of Energy (LCOE) for solar power, making a substantial contribution to renewable energy adoption. Their value will be immense, particularly for utility-scale solar farms with limited land and for rooftop solar systems seeking maximum power generation in restricted spaces. This technology is set to become a powerful driver in accelerating the global energy transition.
