Industry Context

Ascent Solar Technologies operates in the high-value specialty solar markets, including space power beaming, aerospace, satellites, near-earth orbiting vehicles, fixed-wing UAVs, and agrivoltaics. These markets demand highly specialized power generation solutions and offer attractive pricing due to significant technological requirements. The company differentiates itself by focusing on Copper-Indium-Gallium-diSelenide (CIGS) on a flexible, plastic substrate with monolithic integration, claiming to be the only company globally focused on commercial-scale production of this specific technology. This positions Ascent against traditional rigid solar panels and other thin-film solutions like amorphous silicon (a-Si) and cadmium telluride (CdTe), which the company believes have lower efficiency or are unsuitable for flexible applications. The company also notes CIGS's advantage over Gallium Arsenide (GaSa) in cost and weight-per-watt output.

Comparison to Industry Standards

• Ascent Solar Technologies states it is, to its knowledge, the only company in the world currently focused on commercial scale production of PV modules using CIGS on a flexible, plastic substrate with monolithic integration, suggesting a unique market position.
• The company claims its CIGS technology offers a higher demonstrated cell conversion efficiency at the laboratory level compared to amorphous silicon (a-Si) and cadmium telluride (CdTe).
• Ascent highlights that a-Si's conversion efficiency degrades when exposed to UV light, requiring additional manufacturing steps for mitigation, unlike CIGS.
• The company notes that CdTe modules, while comparable in production efficiency to CIGS, have not been successfully applied to a flexible substrate on a commercial scale, making them unsuitable for Ascent's target applications.
• Ascent asserts that CIGS can achieve higher conversion efficiencies in production than CdTe.
• The company also believes CIGS has a more advantageous weight per watt output compared to Gallium Arsenide (GaSa) modules, which are also more expensive.
