New Theory Guide Available: OPVs vs. 2nd-Gen Solar Cell Technologies


Posted on Tue, Sep 18, 2018

The solar cell market is currently dominated by crystalline silicon (c-Si) cells - also known as first-generation solar cells - which are lauded for their high efficiency and well-established manufacturing processes. Despite this, c-Si cells have high costs and a long payback time. As such, this type of solar cell is unlikely to be fully adopted until initial costs are lowered.

On the other hand, commercially-available thin-film solar cells (second-generation) are both affordable and easy to manufacture. This is due to their thin active layers, which use much less material than c-Si cells. They also pave the way for flexible and translucent solar cells.

Beyond the technologies mentioned above are third-generation solar cells - which among others, includes organic photovoltaics (OPVs). This generation encompasses 'emerging' technologies that are less commercially available. OPVs are on their way to achieving efficiencies comparable to those of commercial c-Si cells, and typically have simpler manufacturing processes, higher defect tolerance, and fewer rare or toxic components.
