According to reports, Japanese electronics giant Sharp is planning to mass-produce lightweight, high-efficiency, and low-cost perovskite-silicon tandem solar cells.
Leveraging its experience in OLED manufacturing, Sharp aims to reduce production costs by approximately 10%, making solar energy more affordable than ever before.
Reports indicate that by fiscal year 2027, Sharp will launch these tandem cells, which layer perovskite on traditional silicon to enhance power conversion efficiency by absorbing more light. Perovskite materials are extremely thin and flexible, allowing them to adapt to various locations. Moreover, since they utilize domestically sourced iodine resources, this represents a win for Japan’s energy security. This development is part of a broader movement in Japan and across the Asia-Pacific region to lead the commercialization of perovskite solar technology.
The Japanese government has supported these efforts through substantial investments, while industry players such as Sekisui Chemical and Sharp are advancing research and pilot projects. The practical goal is to achieve large-scale production at low cost, which could further reduce the per-watt price of solar panels as manufacturing scales up.
Sharp has publicly showcased these new tandem cells and demonstrated prototypes at industrial expos, where the company highlighted their potential for installation in space-constrained areas such as electric vehicles or digital signage.
