Which type of solar cell will be more efficient and what is the most efficient type of solar cells and how much is the efficiency?
Dear Rk Naresh , please check

for a comparison of different types of solar cells and their efficiencies. Best regards, Dirk
Monocrystalline solar panels are the most efficient type of panel compared to polycrystalline and thin-film options. Monocrystalline solar panels deliver between 15% to 22% efficiency. Reflection a cell's efficiency can be increased by minimizing the amount of light reflected away from the cell's surface. For example, untreated silicon reflects more than 30% of incident light. Anti-reflection coatings and textured surfaces help decrease reflection. Of the three basic solar panel type’s monocrystalline, polycrystalline and amorphous monocrystalline is the most efficient in collecting solar energy and therefore somewhat more effective in regions with low sunlight. In terms of pure efficiency at harvesting energy from the sun, solar thermal is more efficient at around 70% while PV is around 15-20%. So in theory thermal panels will require less roof space than PV. Concentrated solar technology, or CSP, is a form of solar energy that uses mirrors or lenses to concentrate sunlight onto a small area, creating heat that can generate electricity. CSP is different from traditional solar panels, which convert sunlight into electricity through photovoltaic cells. Monocrystalline solar panels offer better efficiency because they're produced from pure silicon. They have a sleek, black color and produce more power per square foot but are more expensive. Polycrystalline solar panels use multi-crystalline silicon, which results in lower efficiency. The most efficient standard-size panels use high-performance N-type IBC or Interdigitated Back Contact cells which can achieve up to 22.8% panel efficiency and generate an impressive 390 to 440 Watts.
