22.9%! Thin-film solar cell efficiency and record-breaking
Jan 19, 2018
Recently, Japan's solar frontier company (SolarFrontier) said it has set a new record for the efficiency of thin-film solar cells.
In a joint study with Japan's New Energy Industry Technology Development Agency (NEDO), the company achieved 22.9% conversion efficiency using CIS (copper, indium and selenium) technology.
Solar Frontier said the result was 0.3% above the previous record of 22.6%.
This success is attributed to technologies such as CIS absorption design and enhanced surface treatment.
Thin film solar technology can be used to produce flexible panels that are better suited for certain applications than traditional heavier solar equipment.
Previously, researchers achieved a record 35.9% conversion efficiency in Si-based triple junction solar cells.
