Recent research from Oxford University, led by Henry J. Snaith, presents a groundbreaking study on the compatibility of charge extraction multilayer films with carbon electrodes in trans-formed perovskite solar cells. The study highlighted issues related to the compatibility of common electron transport layers with carbon deposition methods, revealing previously unobserved semiconductor characteristics in carbon electrodes. These findings indicate that while perovskite solar cells could achieve high energy conversion efficiencies, they typically rely on costly vacuum-deposited metal contacts, which are often made from precious metals. In contrast, carbon-based materials present a cost-effective and potentially more stable alternative.
In corporate news, JinkoSolar, a major player in the solar cell equipment supply sector, reported a robust performance in Q1 2025, achieving a revenue of 4.099 billion yuan and a net profit of 708 million yuan. The company has recently made strides in technology development, receiving a utility model patent for an “annealing furnace transmission device” on May 9. So far this year, it has secured a total of 41 new patents, with R&D investment increasing by 38.94%. However, concerns have emerged regarding potential short-term stock price fluctuations due to the major shareholder’s plan to reduce their stake by up to 1.8 million shares.
Additionally, Jinau Technology and Jingao Technology have signed a joint venture agreement for a 4GW HBC upgrade project. According to the agreement, the companies plan to establish a new entity in China to produce a total of 4GW of HBC solar cells, with Jinau agreeing to grant the joint venture rights to use its HBC solar cell patent technology. The upgraded facility is anticipated to become a leading HBC production site globally, leveraging advancements in solar cell technology.
In another development, East China Heavy Industry announced the termination of its project to build a 10GW high-efficiency solar cell production base in Bozhou, which was initially proposed in August 2023. The project was ultimately abandoned due to adjustments across the entire industry chain.
Internationally, China is advancing with an ambitious renewable energy initiative dubbed the “Photovoltaic Great Wall,” projected to be one of the largest renewable energy projects in history, with completion expected by 2030. Once finished, it is expected to symbolize a new era of solar energy with a total installed capacity exceeding 880GW, eclipsing that of any other country. China currently holds a dominant position in the global solar panel supply chain, accounting for approximately 80% of production capacity.
Moreover, in Saudi Arabia, companies like Fakeeh Care Group have reported significant savings on electricity costs after installing solar panels at their facilities. The president of the company noted a reduction of over 170,000 riyals in their electricity expenses for 2024, emphasizing that although the initial investment in solar energy is substantial, it is yielding long-term financial benefits while also reducing carbon footprints.
On the financial front, several solar companies are navigating market challenges, with some firms withdrawing their IPO applications while others face delisting due to subpar stock performance. For instance, Jiangsu Meike Solar Technology Co., Ltd. voluntarily requested to withdraw its registration application for public stock issuance, resulting in the termination of its stock listing.
As the solar energy landscape evolves, factors such as solar irradiance remain crucial for photovoltaic generation, directly influencing the energy output of solar panels. The intensity of sunlight determines the energy received by solar cells, thus affecting their current and voltage output.
In recent updates, the U.S. Customs and Border Protection clarified that solar cells are not included in the list of products exempt from equal tariffs, countering previous media reports suggesting otherwise.
