Overview

Trinasolar has announced a new world record, achieving 907W power output and 29.2% full-area efficiency for its perovskite/crystalline silicon tandem module. This breakthrough, based on the company’s 210mm large-area tandem cell technology system, was accomplished through improvements in perovskite film uniformity, interfacial passivation, and spectral absorption matching within the tandem structure. This achievement marks a significant milestone in scaling up and increasing efficiency in the PV industry, poised to greatly enhance the performance of next-generation modules and accelerate the transition to clean energy.

In Depth

Key Findings

Trinasolar, a global leader in photovoltaic (PV) solutions, has set a new world record with its perovskite/crystalline silicon tandem module, achieving an unprecedented 907W power output and 29.2% full-area efficiency. This monumental accomplishment leverages the company’s advanced 210mm large-area tandem cell technology system, representing a significant leap forward in the performance capabilities of next-generation solar modules.

Technical Details

The record-breaking efficiency was achieved through a combination of several key technological innovations: exceptional uniformity of the perovskite thin film, advanced interfacial passivation techniques, and precise spectral absorption matching within the tandem structure. Trinasolar’s R&D team focused particularly on achieving uniform film deposition and suppressing defects across large-area devices, thereby minimizing recombination losses of charge carriers. The attainment of this efficiency in a 210mm large-area format demonstrates strong practical potential for commercial-scale modules, moving beyond small, laboratory-sized cells. This technological advancement simultaneously enhances both the performance and reliability of solar cell modules.

Background & Context

The current solar PV industry is fiercely pursuing both efficiency improvements and manufacturing cost reductions. Tandem technology, in particular, is seen as the key to surpassing the theoretical efficiency limits of conventional single-junction silicon solar cells. Trinasolar’s latest achievement substantiates the immense potential of combining perovskite and crystalline silicon for high-efficiency, large-scale module manufacturing. High power output in large-area modules is critically important for maximizing power generation per unit of installation area and improving project profitability, especially for large-scale solar projects and space-constrained environments.

Strategic Significance & Outlook

The achievement of 907W output and 29.2% full-area efficiency by Trinasolar establishes a new benchmark for the development of next-generation solar cell modules. The company is expected to accelerate the development of large-scale production technologies for commercialization based on this innovation. Such high-efficiency modules are anticipated to further reduce the levelized cost of electricity (LCOE) for solar power systems, vigorously driving the global transition towards clean energy. This achievement represents a vital step towards realizing more powerful and sustainable energy solutions.
