研究目的
Investigating the potential of car-roof photovoltaic (PV) systems to enable 70% of passenger cars to run on solar energy and the suitability of static concentrator photovoltaic (CPV) technology for this application.
研究成果
Car-roof PV has a potential market of 50 GW/year, but high power conversion efficiency is required. Static CPV is a suitable candidate due to its high efficiency and ability to cover curved surfaces. Adjusting the bandgap of the bottom cell can solve spectrum mismatching issues.
研究不足
The study highlights the challenges of achieving high power conversion efficiency and full coverage on three-dimensional curved surfaces. It also notes the sensitivity of multi-junction cells to spectrum matching, particularly in summer.
