"A waste product is transformed into a highly efficient solar module. That's next generation sustainability at its best."

By using cadmium telluride, we actually help the environment during manufacturing – for the cadmium used is a waste product from the mining industry that would otherwise have to be permanently stored at significant cost to rule out environmental impact.

CdTe technology modifies the cadmium with tellurium to produce a water-insoluble semiconductor – a key component of our thin-film modules. The cadmium telluride is securely encapsulated between two glass  substrates in order to reliably produce electricity for decades.

A cubic metre of cadmium telluride will make around 330.000 Calyxo modules and for example in Germany produce 520 GWh of electricity throughout its lifetime. Generating the same amount of energy in a gas-fired power plant would take 80.000m³ of natural gas.

Lifecycle-Management

Maximum quality and compliance with stringent environmental standards are our foremost criteria for ensuring customer satisfaction. The statutory and regulatory requirements in force merely represent the minimum standards for Calyxo. We stand by our product stewardship – including vis-à-vis the next generation – and have made environmental protection a firm part of our mindset and everything we do in order to be able to offer our customers nothing but the highest quality.

At Calyxo GmbH, quality begins long before production in the selection of suppliers – who are measured by our own high standards. Moreover, all employees are instructed about their own environmental responsibility depending on their activities.
