For solar cells

High-Durability Transparent Conductive Films

Transparent conductive film adapted for use with solar cells

Overview

Our transparent conductive films can withstand the high temperatures necessary to manufacture solar energy cells.

Features & Strengths

Point1 Performs better than FTO films

Our films achieve superior transmittance and resistance compared to the FTO films currently used as highly heat resistant transparent conductors.

Substrate materials
High-durability transparent conductive films 10 84.0 Soda-lime glasses
FTO films (for refarence) 10 79.7 Soda-lime glasses

*The above specifications are all customizable.

Point2 Highly resistant to heat

No feature degradation, even when subjected to processes involving firing at 500℃ for one hour

Changes in resistance values and transmittance characteristics after firing at 500℃

  • Heat-resistance characteristics
  • Transmittance characteristics

Point3 Highly resistant to chemicals

Insoluble to acids and alkalines, meaning it can be used with liquid processing and in medicines.

Customization, response to tests

At Geomatec, we use thin-film technology to develop parts for solar energy cells. We will conduct customization and testing in response to your demands.

Contact us-to-Delivery Process

When outsourcing of thin-film coatings to substrates provided by customers

Below is an example of contact us-to-delivery process when outsourcing of thin-film coatings to substrate materials provided by customers. Whether you need a single item prototype or mass production, trust Geomatec to provide high-quality, high-performance thin-film coatings.

  • Step1Contact Us

    For detailed questions regarding our products and solutions, order numbers and specifications, delivery times and budget, areas where delivery is possible, or for any other questions about how we can assist with your objectives and ideas, please feel free to contact us.

  • Step2Discovery & Technical meetings

    After inquiring about the details of your request, we will propose the plan that best allows us to meet your objectives. Of course, Geomatec engineers will collaborate with all kinds of manufacturers, as necessary, to support the creation of a product that meets your standards.

  • Step3Estimates

    We will quote based on the specifications defined in the discovery & technical meetings.
    Please rest assured that information on the intended applications of your product, personal information, or other confidential information we receive will be monitored under a strict information security system.

  • Step4Prototypes & Samples

    We will produce prototypes and samples as required.
    In addition, if you are also considering mass production at some point in the future, we can process your prototype on the same machinery that will be used for mass production, ensuring a smooth transition into the mass production stage and identical quality and features as those seen in the prototype.

  • Step5Thin-film manufacturing (procurement, coating and post process)

    We will apply thin films to substrate materials provided by customers and carry out high-quality, stable manufacturing and processing in a class 100 to 1,000 clean room (as defined in Federal Standard 209D).

  • Step6Quality inspection & Shipping preparation

    We conduct quality inspections of all the products we provide our customers and provide packing according to strict standards.
    Geomatec has acquired certification for its QMS (ISO9001: quality management system) and endeavors to provide safe and stable delivery of high-quality products.

  • Step7Delivery

    We will reliably deliver our products to any location, by any method, and on any day you specify.

    *We offer a flexible range of options other than the above, including in-house consultation on site at customers' factories.

When outsourcing of substrate material procurement and post coating process, in addition to thin-film coating

The following is an example of contact us-to-delivery process when outsourcing of substrate material procurement and post coating process, in addition to thin-film coating. Geomatec will control all steps of the process.
