According to PV InfoLink data, the combined market share of 182mm and 210mm large-size solar cells accounted for nearly 90% of the total market share in 2022, establishing themselves as the industry standard. In the direction of large-size development, various PV module manufacturers have pursued di
LECO (Laser-enhanced contact optimization) can improve efficiency by 0.2-0.5% by reducing contact resistance and enhancing cell efficiency. LECO is an advanced laser sintering technique used to improve the contact between metal electrodes and silicon wafers in solar cells. In LECO processing, lasers
Recently, Canadian Solar delivered the first batch of 700W TOPCon solar panel to solar distributors in the United States. In a comprehensive technical assessment, Canadian Solar TOPBiHiKu6 (182mm silicon wafer) and TOPBiHiKu7 (210mm silicon wafer) series bifacial solar modules, boasting an industry-
In recent years, with the continuous development of solar technology, TOPCon solar cells have emerged as a promising player in the market. It is anticipated that in 2024, the market penetration of TOPCon solar cells will experience a significant boost. This technology adopts a tunneling oxide layer
In 2023, high electricity prices and growing demand for electric vehicles and heat pumps fueled significant solar growth. Boosted by a new government subsidy, both small and large-scale solar systems contributed to this surge.Swissolar predicts Switzerland's cumulative PV capacity will surpass 6.2 G
According to the revised EPBD (Energy Performance of Buildings Directive), EU member states are required to reduce the average primary energy consumption of residential buildings by 16% before 2030 and by 20-22% by 2035. Each country can choose specific buildings and measures to achieve these target
On the evening of December 14th, Aikang Technology announced plans to invest 2.1 billion yuan in constructing six HJT (Heterojunction) cell production lines, with a combined capacity of 4.6 GW. According to the announcement, the investment will be made by Aikang Technology's wholly-owned subsidiary,
At last week's World Future Energy Summit and Exhibition (WFES), companies carefully selected solar panels for display, all sharing a common feature: Big size! From the exhibition, it is clear that the mainstream power range of solar panels in the Middle East generally falls into two categories: 550W-580W and 600W-670W. Most will choose double-sided, long-cable modules using N-type TOPCon technology.

Recently, Khajeh Nasir Toosi University of Technology in Iran released a report stating that they achieved a power conversion efficiency of 27.63% by using Perovskite materials methylammonium lead iodide (MAPbI3) and molybdenum ditelluride (MoTe2), and altering the nanostructure into a V shape for "enhanced light absorption." They note that MoTe2, in particular, has the potential for "cost-effective manufacturing" and "benefits from other promising properties such as tunable band gap, high carrier mobility, non-toxicity, earth-abundancy, and stability and durability."

Recently, an article in the US media has stirred up a heated discussion among the public regarding the safety of solar plants. The article points out that solar panels may suffer from damage and performance reduced , or even the stable operation of the entire plants affected, when subjected to severe hailstorms. Even more worrying is the concern that harmful substances such as cadmium telluride may leak from the broken panels, potentially contaminating nearby water sources, weighing heavily on people's minds. At this critical juncture, the Solar Energy Industries Association (SEIA) in the United States has promptly released an authoritative report to address public concerns.

The lifespan of a solar power station is generally more than 25 years, and it is inevitable to encounter various extreme environments. How to ensure the continuous and stable power generation of solar modules should be everyone's biggest concern. In summary, qualified solar panel need to pass at least seven tests, including electrical performance testing, optical performance testing, mechanical performance testing, durability testing, temperature coefficient testing, reflectance testing, dimension and weight testing. Solar panels that pass these tests are considered to have a factory "passport", but to achieve superior performance, they also need to address tests such as temperature coefficient testing, dynamic mechanical load testing, lead testing, humidity resistance, and corrosion resistance testing, among others. The aforementioned hail load test belongs to a type of dynamic mechanical load testing.
