FAQs

What is the process of manufacturing solar panels from polysilicon?

The manufacturing process begins with the purification of metallurgical-grade silicon into high-purity polysilicon via the Siemens process or fluidized bed reactor technology. This polysilicon is then melted and crystallized into large cylindrical ingots using either the Czochralski method for monocrystalline or directional solidification for multicrystalline silicon. These ingots are then squared and sliced into ultra-thin wafers using diamond-wire saws. The wafers undergo several cleaning and texturing steps before being processed into photovoltaic cells through doping, coating with anti-reflective layers, and screen-printing metal contacts. Finally, these cells are interconnected, laminated between glass and polymer sheets, framed, and junction-boxed to create a finished, weatherproof solar module.

What are the different types of solar wafer materials?

The predominant material for solar wafers is crystalline silicon, which is divided into two main types: monocrystalline silicon and multicrystalline (or polycrystalline) silicon. Monocrystalline wafers are cut from a single, pure crystal ingot, resulting in higher efficiency and a uniform black appearance. Multicrystalline wafers are made from a block of multiple silicon crystals, which makes them less efficient but historically more cost-effective to produce. While other materials like thin-film cadmium telluride (CdTe) or copper indium gallium selenide (CIGS) exist, they are not made from silicon wafers and represent a different technological pathway for creating photovoltaic cells.

Who are the leading manufacturers of solar ingots and wafers?

The market for solar ingots and wafers is highly concentrated, with a few companies commanding the majority of global production capacity. LONGi Green Energy Technology is the undisputed global leader in monocrystalline wafer production. Other major manufacturers include Zhonghuan Semiconductor (TZS), which is also a significant player in the wafer segment, and Jinko Solar, which is vertically integrated and produces wafers for its own cell and module production. Companies like GCL-Poly and Tongwei, while known primarily as polysilicon giants, also have substantial involvement in the downstream ingot and wafer markets.

How does PERC technology improve solar cell efficiency?

PERC (Passivated Emitter and Rear Cell) technology enhances solar cell efficiency by adding a passive dielectric layer on the rear surface of the cell. This layer passivates the rear surface, meaning it reduces the recombination of electrons that would otherwise be lost as heat. It also increases internal reflectivity, allowing light that passes through the silicon without being absorbed the first time to be reflected back for a second chance at absorption. These combined effects allow the cell to generate more electrical current from the same amount of sunlight, typically boosting efficiency by an absolute 1% or more compared to standard Al-BSF (Aluminum Back Surface Field) cells.

What are the key applications for solar modules beyond rooftop installations?

Beyond residential and commercial rooftops, solar modules have vast utility-scale applications, constituting the largest segment by volume. These include massive ground-mounted solar farms that feed power directly into the electrical grid. Emerging and specialized applications are also gaining prominence. These include floating solar farms installed on reservoirs, ponds, and lakes, which save valuable land and reduce water evaporation. Building-integrated photovoltaics (BIPV) are another key application, where solar elements are seamlessly incorporated into building materials like roofing tiles, facades, and skylights. Solar modules are also used in off-grid applications for powering telecommunications equipment, agricultural irrigation systems, and remote community microgrids.

Which regions are the largest producers and consumers of solar PV products?

China is overwhelmingly the largest producer of solar PV products, dominating the manufacturing of polysilicon, ingots, wafers, cells, and modules, accounting for a dominant share of global production capacity. In terms of consumption, Asia-Pacific is also the largest regional market, driven by massive installations in China, India, Japan, and Vietnam. However, significant demand also comes from North America, led by the United States, and Europe, where countries like Germany, Spain, and the Netherlands are major consumers. While production is highly concentrated in Asia, consumption is more globally distributed, driven by local renewable energy policies and electricity demand.
