LDK Solar Co., Ltd. (OTCMKTS: LDKYQ) was a vertically integrated manufacturer of multicrystalline silicon wafers for the global photovoltaic industry. Founded in 2006, the company quickly built large‐scale production facilities in Yanggu, Shandong Province, China, focusing on the ingot growth and wafer slicing processes that form the foundation of solar cell manufacturing.
The company’s core offerings included multicrystalline silicon ingots and wafers ranging in size from 6‐inch to 8‐inch diameters, which were sold to downstream cell and module producers across Europe, North America and the Asia‐Pacific region. At its peak, LDK Solar supplied millions of wafers annually and explored opportunities in solar cell and module integration to diversify its product portfolio.
In 2007, LDK Solar completed an initial public offering on the NASDAQ, raising capital to expand capacity and invest in continuity of supply. However, industry oversupply and margin compression in the early 2010s strained the company’s finances. In 2014, LDK Solar filed for Chapter 15 bankruptcy protection in the United States and was subsequently delisted from major stock exchanges, marking a significant restructuring of its operations.
Under the leadership of Founder, Chairman and CEO Xiaofeng Peng, LDK Solar played a pioneering role in driving down the cost of multicrystalline silicon wafers, contributing to the broader affordability and adoption of photovoltaic technology worldwide. Although LDK no longer maintains large‐scale commercial operations, its early expansion and technological developments helped shape supply chains in the solar manufacturing sector.
