Inventions & Innovators powering the Energy Transition – Next Generation Solar
Next Generation Solar Technologies
The dominant PV technology today is the crystalline silicon-based cell. Making up somewhere in the region of 90% commercial market share, the benefits include the maturity of the technology, proven reliability & performance from over 50 years of use and availability of the raw material silicon.
In this, the second of a series to put a lens on the invention and innovations being made in critical technologies powering the energy transition, we take a look at next generation solar with a focus on new innovations specific to photovoltaic cells:
- Thin-film PV Cells: with about 10% market share and characterised by thin layers of photovoltaic materials deposited onto substrates such as glass or flexible plastic sheet. The principal types include Copper indium gallium selenide (CIGS), Amorphous Silicon and Cadmium Telluride (CdTe).
- Organic PV Cells: an emerging category that utilises carbon-based semiconductors. Yet to be commercialised but attracting a lot of interest due to the relatively low cost and manufacturing flexibility. Key challenges to overcome include low power efficiency and short material life.
- Perovskite PV Cells: materials with the same crystal structures as calcium titanium oxide (CaTiO3). The first use as a photovoltaic material was in 2009 with rapid progress made in improving power conversion efficiency. Perovskites offer relatively high performance and low production cost potential.Whether you are an energy supplier, consumer, innovator or investor understanding in which technology areas the inventions are being made and who owns these inventions is the starting point for getting ahead and taking advantage of the changes that are coming
