Path to Unlocking the Full Potential of Photovoltaic Power Generation
The solar energy industry has seen an extremely rapid development in the past decade. In 2019 alone, we saw over 140 GW of new photovoltaic (PV) power generation capacity installed, leading to the total global PV power generation capacity of 583.5 GW (580.1 GW on-grid and 3.4 GW of off-grid [1]) at the end of 2019. This means more than one fifth of renewable energy in the world today is generated by PV technology.However, whilst it is only in recent years that we have witnessed a dramatic improvement of the technical and economic feasibilities of PV power generation, it should be remembered that such improvement is an achievement enabled by nearly two centuries of technical and commercial development.
