Exhibition: 1.54 Million Nanometers of DSSC

The exhibited works will be based on dye-sensitized solar cell (DSSC) technology.

Currently, the most advanced semiconductor manufacturing process is at 2 nanometers, but the unique name “1,540,000 nanometers” reflects the concept symbolized by the spirit of DIY. This exhibition is a site-specific project inspired by the concept of “off-grid,” integrating the artist’s experience in creating dye-sensitized solar cells (DSSC) using plant-based dyes with new works.

The concept of “off-grid” not only refers to renewable energy independent of the power grid but also encompasses decentralized thinking, such as blockchain and DIY activities, in a more abstract sense. Dye-sensitized solar cells (DSSC) are a relatively easy-to-make, low-cost third-generation solar technology, where the mechanism of power generation is deeply linked to dyeing techniques. Their performance is determined by the absorption of pigments, which can be achieved using either natural or chemical dyes. One of the installations of this exhibition combines DSSC solar technology with blockchain technology, exploring the possibilities of energy tracking and exchange through rapid prototyping based on the concepts of “energy = instant information” and “symbiosis between energy and plants.”

Furthermore, the act of DIY production itself is considered a form of artistic expression, leading to the creation of a series of small books and photo collections made with DSSC technology and glass. One of these books documents the DSSC manufacturing process and its technical details. The text in these books is printed directly onto the semiconductor layer of the DSSC using cyanotype (blueprint) technology with laser light, making them not only art pieces but also functional solar cells. This work demonstrates the intersection of craftsmanship and practical power generation technology. 

This project is still ongoing, and the artist aims to share the latest progress with the audience, fostering discussions on energy art. Additionally, the exhibition provides an opportunity to exchange knowledge about DIY solar panel manufacturing techniques, along with insights into the discoveries and challenges encountered during the research and prototyping process.
