Microlink Devices hits 37.75% efficiency for triple junction cell

Multi-junction cells are going to be the standard. Perovskite+silicon is moving into the factories from the labs right now and getting pushed hard by multiple companies. High end multi-junction products have been in space for decades. The challenge is that most of them – like this 37% project talked about today – are using expensive materials – and so the solar panels cost $5-8/W, a big difference from our current 30-70¢/W. How long until you and I have a solar panel above 25% making use of multijunction? Five years minimum…unless you got a lot of money and are ready to invest for the rest of us.

SOURCEMicrolink’s ELO production process involves the peeling off of thin active cell layers from a gallium arsenide substrate, and is combined with multi junction technology, integrating three or more semiconductor layers. While the company points out that the substrates made from costly gallium arsenide can be reused to keep costs down, it is unlikely the cells will be cheap enough for application outside of UAVs, satellite and other areas requiring very lightweight solar cells.

About John Fitzgerald Weaver

John Fitzgerald Weaver is a solar developer; known digitally as the 'Commercial Solar Guy.' As a project developer and installer, he’s sold and managed 50+ solar projects, valued over $25 million, ranging in size from 5kW to 1500kW. He’s been involved in many aspects of the solar supply chain –- as a company founder, developer, project manager, manufacturer, permit runner, salesman, contractor and financier. In his free time he tries to get away and clear his mind by climbing mountains, or more regularly by enjoying an IPA or scotch, and really loves the strange connection between politics, energy, finance, and environment in the energy world.
