Photovoltaic (PV) efficiency refers to the ability of a photovoltaic device, such as a solar cell or solar panel, to convert sunlight into usable electrical energy. It is expressed as a percentage and represents the ratio of electrical power output to the amount of sunlight (solar energy) input.
Trends in photovoltaic (PV) efficiency improvement include incremental advances, the emergence of tandem solar cells stacking multiple materials for enhanced efficiency, the growing prominence of perovskite solar cells due to rapid efficiency gains, and the increasing popularity of bifacial solar panels capturing sunlight from both sides.
Enhanced efficiency, achieved through a decade of progress, has driven the global expansion of solar PV. Multi-junction photovoltaic materials have now exceeded 40% efficiency in lab tests. China leads the world in solar PV installations, boasting over 253 GW of installed capacity by the end of 2021.
Technologically, the main challenge for the photovoltaic industry is improving PV module energy conversion efficiencies. Therefore, a variety of techniques have been tested, applied and deployed on PV and PV/T systems. Combined methods have also been a crucial impact toward efficiency improvement endeavors.
Systems using solar photovoltaic energy are also getting cheaper and more effective. The cost of solar panels has dropped significantly in recent years, and the efficiency of solar cells has also grown 2. Now, solar photovoltaic systems can generate more power for a lower cost.
Breakthroughs in emerging solar cells, as shown in Figure 13, have achieved efficiency records of 25.5% for perovskite cells, 29.5% for perovskite/Si tandem cells, and 18.2% for organic cells, while research tendencies focus on improving efficiency, stability, and scalability.
