On 12 August 2008, centrotherm photovoltaics AG announced a two-year research-and-development project budgeted at approximately €10 million. It was intended to develop a new generation of solar cells and the production processes needed to make them, with significant efficiency improvements as the goal. The company did not publish a numeric efficiency target or a project-specific commercial result.
What did centrotherm invest €10 million in?
The announced investment supported a coordinated, cross-group R&D effort—not a single factory-equipment order. More than 25 experts from across centrotherm’s solar-cell-production activities were assigned to work on cell development and related manufacturing processes. The announcement was issued in Blaubeuren, Germany, on 12 August 2008. Centrotherm’s 2008 announcement described the budget as approximately €10 million over two years.
What technologies and processes were in scope?
The company highlighted both mono-crystalline and multi-crystalline silicon cells, as well as process improvements for conventional cells. The project therefore addressed two connected parts of production: the cells themselves and the methods for manufacturing them.
That combination is significant for industrial production. A cell-design improvement has commercial value only if the process can produce it consistently at factory scale. The announcement framed the work around that broader challenge rather than naming one piece of equipment or a single cell architecture.

- 🏞️【Built for Low-Power Solar Experiments】These solar cells are suitable for learning series or parallel layouts, comparing output, and building simple 5V solar panel projects.
- 🏞️【Match Before You Connect】Designed for low-current devices, each 1W solar panel should be used with the proper circuit, polarity, and sunlight conditions for better project results.
How much efficiency improvement was expected?
Centrotherm said significant efficiency improvements were the intended outcome, but its accessible announcement gives no percentage target. It also does not state a production-volume goal, revenue forecast, or return-on-investment figure. Any specific efficiency number attributed to this project would go beyond the published details.
Did the project produce a commercial solar cell?
The available company materials do not identify a commercial cell or product as a direct result of the 2008 project. Centrotherm’s later corporate history describes integrated process technology for high-efficiency PERC, IBC, and TOPCon cells, and says it established centrotherm Solar technology (Yiwu) Co. Ltd. in 2020 for cooperative R&D with customers and partners. That history shows the company’s continuing involvement in photovoltaic process technology, but it does not establish that the 2008 project directly created any one later product.

How does the announcement relate to centrotherm today?
Centrotherm is an industrial supplier, not a consumer solar-panel brand. Its current corporate materials describe integrated production solutions and thermal process technology for high-efficiency photovoltaic cells. A 2026 corporate-news item reports that six PECVD systems were selected for a 1.2 GW TOPCon line in India, an example of the large-scale, business-to-business manufacturing projects in which the company operates. The item illustrates present-day activity; it does not link that project to the 2008 investment. Centrotherm’s 2026 corporate news
