Leading PV manufacturer JinkoSolar has announced that its high-efficiency advanced cell based on TOPCon technology has achieved a certified maximum conversion efficiency of 27.79%, according to Germany’s ISFH. The company claims this is its 31st world record in cell efficiency or module power. JinkoSolar attributes the latest breakthrough to its new passivated contact architecture, ultra-low optical parasitic absorption, and next-generation metallization processes.
Also, the company recently held a mass-production launch ceremony for its new-generation TigerNeo 3.0 module series. According to JinkoSolar, the product reaches a mass-production efficiency of over 24.8%, delivers up to 670 W of power, and offers a bifaciality of up to 90%. The company claims it has signed 15 GW of contracts for these modules.
In June, Jinko had announced that its 182 mm n-type monocrystalline silicon TOPCon cell achieved a certified full-area conversion efficiency of 27.02% (see China Solar PV News Snippets).
Last month, JinkoSolar signed a comprehensive strategic cooperation agreement with DKEM, aiming to collaborate on technological innovation for high-efficiency solar cell metallization paste and on low-silver/silver-free metallization technologies for solar cells (see China Solar PV News Snippets).
Anhui Province has released the results of its 2025-2026 renewable mechanism electricity tariff auction. The auction targeted new energy projects achieving full-capacity grid connection between June 1, 2025, and December 31, 2026, with an originally planned mechanism electricity quota of 9 billion kWh. However, at only 5.87 billion kWh awarded, the auction ended undersubscribed, including 4.02 billion kWh for solar PV and 1.85 billion kWh for wind.
Winning projects were divided into independent bidding and unified bidding (solar and wind at the same tariff). Independent bidding projects accounted for 4.113 billion kWh at a price of RMB 0.3837/kWh, while unified bidding awarded 1.755 billion kWh at RMB 0.384/kWh. All selected projects will apply the awarded tariff for 12 years.
In contrast to Anhui’s shortfall, Heilongjiang Province achieved full subscription in its 2025-2026 mechanism electricity price auction. According to the published results, the full quota of 6.30 billion kWh for PV and wind projects scheduled for commissioning between June 1, 2025, and December 31, 2026, was fully allocated. This includes 5.27 billion kWh for centralized onshore wind, 998 million kWh for centralized solar PV, and 34.38 million kWh for distributed PV.
All winning projects will apply a uniform mechanism tariff of RMB 0.228111/kWh for a 12-year period.
A subsidiary of China Energy Engineering Corporation (Energy China or CEEC) has begun installing its first self-developed integrated photovoltaic noise-barrier project. Positioned as the country’s first demonstration combining solar power generation with noise-reduction technology in the power sector, the project deploys a 1-meter-high single-sided PV noise barrier along a 538-meter wall. The exterior side houses the PV generation units, while the inner side adopts a sound-absorbing and insulating structure. The project has a total installed capacity of 107 kW.
According to the company, the solution integrates intelligent algorithms for structural design and system configuration, overcoming the traditional limitation of noise barriers serving only acoustic purposes. It added that testing showed that the system enhances sound insulation by 5-6 dB compared to conventional noise barriers. The single-sided system achieves a noise-reduction coefficient (NRC) of above 0.85, while the bifacial version improves low-frequency noise attenuation by over 50%, making it suitable for highways, substations, and other noise-sensitive environments.
Earlier this year, Gezhouba Group Transportation Investment (CGGC), another subsidiary of energy and power developer Energy China, commenced construction of a highway transport-energy integration project with 8.524 MW capacity (see China Solar PV News Snippets).
