Photowatt

Photowatt presentation

Historic pionner of the solar industry for 40 years, today we are a leader in the production of low carbon ingots, wafers and high efficiency photovoltaic modules.

Manufacturing process

Silicium

Silicon

Silicon produced from quartz, melted into ingots at 1500 ° C and crystallized.

Lingot

Ingot & bricks

The ingots are cut into bricks before the polishing process and infrared inspection through silicon.

Labfab process (wafer)

Wafer

The bricks are cut into slices of
170 to 190 µm to produce LOW CARBON wafers.

Cellules photovoltaïques

Cell

Texturization of wafers, p / n junction created by phosphorus diffusion, anti-reflection layer, contacts (metallization) serigraphs on both sides.

Module

The cells are assembled by historical partners of Photowatt.

Recycling

Photowatt is co-founder of SOREN, a solar panel is 96% recyclable.

Timeline

Photowatt en 1979

1979

Starting up as a research organization

Creation of Photowatt as a research center as a spin-off from Philipps (development of photovoltaic cells for satellites)

Anciens fours Photowatt

1984

Photowatt becomes producer

The company will broaden its vocation and take on an industrial dimension. Photowatt switches from 4-inch monocrystalline cells to multicrystalline silicon, thanks to the POLIX melting process that it has designed and industrialised itself. At the same time, it initiates the development of the first wire saws, used today by most manufacturers in the sector.

1990

Moving to Rhône-Alpes

The company moves to Bourgoin-Jallieu to expand and get closer to the industrial and research centres of Lyon and Grenoble in the Rhône-Alpes region. Photowatt remains a company with a production capacity of 3 MWp.

1997

New industrial dimension

The capacity is increased to 13 MWc, following the acquisition of the company by ATS. In 2001, Photowatt increases its wafer and cell manufacturing capacity and acquires a photovoltaic module assembly line.

2000

Photowatt in the world's top 3

With Siemens and BP (Solarex) on Monocrystalline and Polycrystalline technologies.

Photowatt PV Alliance

2007

Launch of PV Alliance

Launch of PV Alliance with EDF ENR and CEA within Photowatt to develop high efficiency cells.

EDF Photowatt

2012

Integration into the EDF Group

Photowatt and PV Alliance become 100% subsidiaries of EDF Renewables.

cellule photovoltaïque Advanced Crystal

2016

Crystal Advanced® Technology

Launch of modules and cells in Crystal Advanced® monolike technology, which offers high performance at low cost and a low carbon footprint.
