About Us
Over 20 years dedicated to solar PV, delivering high-quality photovoltaic solutions to customers worldwide.
JOYOSOLAR
JOYOSOLAR was founded in 2022 at the Wuhan Overseas Students Entrepreneurship Park. The founding team has dedicated years to perovskite photovoltaic technology, driven by the ideal of contributing to the nation through academia. The company is committed to the design and development of perovskite material technology, perovskite photovoltaic modules and processes, related equipment, low-carbon manufacturing, and market-oriented applications. Based on verifiable technical indicators, the company will develop phased products and actively promote the early industrialization of low-cost, high-efficiency new perovskite photovoltaic technology, providing new technical options for achieving the goals of carbon peak and carbon neutrality.

Process & Showcase Flow
Mass Production Process

Slot-Die Coating
Slot-die coating moves perovskite modules from lab to GW-scale production. A precision die extrudes precursor solution through a micron-level gap for uniform large-area films, supporting rigid and flexible substrates with nanometer-level thickness control. Combined with in-situ crystallization control and an air knife, it eliminates edge effects and pinholes and keeps dead area below 3% in a 0.6m x 1.2m module, enabling high-yield, high-uniformity production at lower cost per watt.
