SolaReactor Solar Cell Diffusion Furnaces

Project Description

The SolaReactor offers leading edge technology Plasma Enhanced Chemical Vapor Deposition (PECVD) and POCl3 Deposition systems designed to optimize throughput and enhance cell efficiency in the production of photovoltaic films

Designed specifically for the solar industry, the SolaReactor deposits a superior PECVD AR film and low sheet resistance POCl3 deposition to produce highly efficient solar cells. The SolaReactor provides increased yields and superior reflective value films, compared with atmospheric TiNitride process. The SolarReactor includes a baseline process to produce one of the most efficient AR coatings available. The POCl3 configuration controls the sheet resistance to a high degree of accuracy.
