The Technology Race Behind Photovoltaic Efficiency Breakthroughs: Observing Industry Trends from JinkoSolar's Inclusion in Fortune China Tech 50

The Technology Race Behind Photovoltaic Efficiency Breakthroughs: Industry Trends as JinkoSolar Enters Fortune China Tech 50

The global photovoltaic industry is undergoing a new round of technological iteration. In June 2026, JinkoSolar was selected for the Fortune China Tech 50 list due to its continuous innovation in N-type TOPCon and tandem cell technologies. The company also maintained its leading position in global module shipments in 2025 and the first quarter of 2026, with cumulative shipments surpassing 400 GW. This achievement not only reflects the technical strength of a single company but also points to the accelerating trend of the photovoltaic industry moving toward higher efficiency and lower costs.

Industry Background: PV Technology Enters a New Phase of "Efficiency Competition"

Since 2020, the photovoltaic market has been transitioning from P-type PERC to N-type TOPCon, HJT, and other high-efficiency cell technologies. According to data from the International Energy Agency (IEA), global newly installed photovoltaic capacity exceeded 500 GW in 2025, with N-type technology accounting for over 60% of the total. In terms of efficiency improvements, laboratory tandem cell efficiency has already surpassed the 35% mark, while the efficiency limits of mass-produced modules are being continuously approached. Among JinkoSolar's 32 world records, the latest is a 34.82% conversion efficiency for N-type TOPCon-perovskite tandem cells, marking the transition of crystalline silicon-perovskite tandem technology from the laboratory to the pilot stage.

Current Developments: JinkoSolar's Technology Path and Market Performance

JinkoSolar's technological reserves are reflected in its global portfolio of over 5,700 patents, including more than 3,500 granted patents and over 700 patents related to N-type TOPCon. The company states that its Tiger Neo 5.0 modules achieve a power output of 700W at the same size, with a module efficiency of 25.91%, approaching the theoretical efficiency limit of 28.7% for TOPCon crystalline silicon cells. Over the next five years, JinkoSolar has outlined a clear efficiency improvement roadmap, aiming to push the Tiger Neo series toward the theoretical limit.

On the market side, as of the first quarter of 2026, cumulative shipments of the Tiger Neo series reached 240 GW, with an annual target of 75-85 GW. If achieved, total annual shipments would exceed 300 GW. This volume indicates that high-efficiency technology is transitioning from a differentiated product to a market mainstream.

Impact on the Energy System: Lower Levelized Cost of Electricity and Faster Deployment

The continuous improvement in photovoltaic module efficiency directly reduces the system-level levelized cost of electricity (LCOE). According to research from the U.S. National Renewable Energy Laboratory (NREL), every 1 percentage point increase in module efficiency can lower costs for supporting land, racks, and cables by approximately 3-5%. For large-scale ground-mounted power plants, using modules with over 25% efficiency can reduce land use by 15-20%, simplifying approval and infrastructure complexity.Higher efficiency also brings advantages for distributed photovoltaics: generating more electricity on limited rooftop areas, improving the economic viability of commercial and industrial users. JinkoSolar's Tiger Neo series has been widely deployed in multiple GW-scale projects globally, including desert power plants and rooftop projects in the Middle East, China, and Europe.

From the grid's perspective, the widespread adoption of high-efficiency modules helps increase power generation under the same inverter capacity, improve the capacity factor of power stations, and thereby enhance the ability of renewable energy to replace baseload power sources.

Challenges Faced: Efficiency Limits, Mass Production Consistency, and Cost Pressure

Although laboratory data is impressive, maintaining efficiency and controlling costs in mass production remain common industry challenges. TOPCon cells require delicate passivated contact processes and high-quality silicon wafers, demanding extremely high standards for production equipment and material purity. While JinkoSolar has achieved a module efficiency of 25.91%, moving further toward the theoretical limit of 28.7% requires solving engineering issues such as wafer minority carrier lifetime, metal contact recombination, and light-induced degradation.

For tandem cell technology, the stability of the perovskite layer, uniformity of large-area preparation, and encapsulation durability have yet to fully meet the 25-year lifespan standard required by the industry. The IEA's 2025 Technology Roadmap points out that the commercialization of tandem photovoltaics may not be realized at scale until after 2030.

In addition, global overcapacity in photovoltaic manufacturing has led to continuously declining module prices. As of early 2026, monocrystalline PERC module prices have fallen below $0.08/W, while the premium for TOPCon modules has narrowed to $0.01–0.02/W. Cost pressures force companies to find a balance between improving efficiency and reducing costs.

Future Outlook: Technology Route Divergence and Global Competition

Over the next 5–10 years, photovoltaic technology will show diversified development. TOPCon, leveraging its mature industrial chain, is expected to become the absolute mainstream before 2028; HJT and BC technologies may maintain advantages in certain scenarios; while tandem cells will require time beyond 2030 to achieve large-scale substitution. JinkoSolar's roadmap indicates that it will gradually introduce perovskite tandems based on TOPCon, but actual mass production timelines depend on technological breakthroughs and return on investment.

From a global competitive landscape, Chinese photovoltaic companies still dominate capacity and technology, but the US, India, and Europe are promoting self-sufficiency through the Inflation Reduction Act (IRA) and local manufacturing subsidies. JinkoSolar operates factories in the US and Southeast Asia to circumvent trade barriers, but geopolitical risks remain a long-term variable.

Ultimately, the marginal benefits of photovoltaic efficiency improvements will gradually diminish, but when module efficiency exceeds 30%, the transformation of the energy system will enter an accelerated phase. The case of JinkoSolar Energy demonstrates that sustained R&D investment and large-scale production are the core drivers of change.
