CIGS Technology and Manufacturing Process

Siva Power, Inc. specialized in the development and manufacturing of thin-film photovoltaic modules based on copper indium gallium selenide (CIGS) technology. As an American solar power company, Siva Power focused on designing and producing these specific photovoltaics, distinguishing its product line through the use of CIGS semiconductor materials. The company’s operational model centered on the integration of material science and manufacturing engineering to produce efficient solar cells. Siva Power held the operator role for its production facilities, aiming to capture a significant share of the solar market through its proprietary thin-film approach. The company was established with a commissioning date of 2006, marking the beginning of its active development phase in the solar energy sector. Despite its technological focus, the company’s operational status is now recorded as cancelled, reflecting the challenges faced by thin-film manufacturers in the competitive solar landscape.

Rapid Thermal Co-evaporation Process

The core of Siva Power’s manufacturing methodology was the Rapid Thermal Co-evaporation (RTC) process. This technique involves the simultaneous deposition of copper, indium, gallium, and selenium onto a substrate in a vacuum chamber. The "rapid thermal" aspect refers to the high-temperature treatment applied to the deposited layers, which helps to optimize the crystal structure and electrical properties of the CIGS film. This process allows for precise control over the thickness and composition of the semiconductor layer, which is critical for achieving high conversion efficiencies. The co-evaporation method ensures that the four elements are deposited in a single step, reducing the complexity and time required for module production compared to sequential deposition techniques. Siva Power’s engineering team designed this process to be scalable, allowing for the production of large-area modules with consistent quality. The RTC process is known for its ability to produce high-quality CIGS films with minimal defects, which can enhance the performance and longevity of the solar cells.

Glass Substrates and Module Design

Siva Power utilized glass substrates as the foundation for its CIGS photovoltaic modules. Glass provides a stable, transparent, and durable base for the thin-film layers, allowing sunlight to pass through to the CIGS absorber layer. The use of glass substrates also contributes to the mechanical strength and environmental resistance of the modules, making them suitable for a variety of installation environments. Siva Power’s module design likely involved multiple layers, including a back contact, the CIGS absorber layer, a buffer layer, a window layer, and front contacts, all deposited on the glass substrate. The choice of glass as a substrate is common in thin-film solar technology due to its cost-effectiveness and optical properties. Siva Power’s engineering focus on glass substrates allowed for the production of lightweight and flexible modules, which can be advantageous in certain architectural and industrial applications. The company’s manufacturing process was designed to maximize the efficiency of the CIGS film on the glass substrate, ensuring high light absorption and electron collection.
