Analysis for efficiency potential of high‐efficiency and next‐generation solar cells

Abstract This paper overviews photovoltaic R&D projects in Japan. Recently, world‐record and second highest efficiencies of various types of solar cells have been demonstrated under the New Energy and Industrial Technology Development Organization Project: 44.4% (under concentration) and 37.9% (under 1 sun) InGaP/GaAs/InGaAs inverted metamorphic 3‐junction solar cells by Sharp, 26.7% single crystalline Si heterojunction back‐contact solar cell by Kaneka,

Efficiency increased to 15.2% for ultra‐thin Cu(In,Ga)Se2 solar cells

Abstract We improved the efficiency of ultra‐thin (0.49‐μm‐thick) Cu(In,Ga)Se2 solar cells to 15.2% (officially measured). To achieve these results, we modified growth conditions from the 3‐stage process but did not add post‐deposition treatments or additional material layers. The increase in device efficiency is attributed to a steeper Ga gradient in the CIGS with higher Ga content near the Mo back contact,

Field experience and performance analysis of floating PV technologies in the tropics

Abstract The interest in floating photovoltaic (FPV) power plants has grown rapidly in recent years. In many established and emerging markets, such as Japan, South Korea, UK, China, and India, FPV is already considered as an attractive and viable option for PV deployment. In 2016, Singapore launched the world’s largest FPV testbed, with a total installed capacity close to 1 MWp.

Adding an Inert Polymer to Plastic Solar Cells Enables High Efficiency and Easy Production

Polymer plastic solar cells remain an industry priority because of their light weight, flexibility and cost-effectiveness. Now scientists from Stony Brook University and the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have demonstrated that these types of solar cells can be more efficient and have more stability based on new research findings. Led by Miriam Rafailovich, PhD, a Distinguished

SMA System Technology Deployed in Europe’s Largest Battery Storage Project

SMA Solar Technology AG (SMA) has supplied the entire system technology for Europe’s biggest battery storage power plant in Pelham, England. The large-scale storage system in the county of Hertfordshire, with a connected load of more than 60 MVA, is one of a number of projects currently under construction in England to provide the reserve power necessary for frequency control
