Solar cells exhibiting improved conversion efficiency are disclosed. Particularly, multi-pn junction solar cells that contain a current spreading layer as well as concentrating photovoltaic modules that include such a solar cell and light concentrating optics are disclosed. The multi-pn junctions in ...
Single-junction flat-plate terrestrial solar cells are fundamentally limited to about 30% solar-to-electricity conversion efficiency, but multiple junctions and concentrated light make much higher efficiencies practically achievable. Until now, four-junc
Of particular interest for PCE gains, the guest component can also broaden the spectrum of light that can be absorbed. By selecting a guest material that absorbs light in a range not covered by the donor or acceptor, the overall sunlight absorption of the cell can be increased. Meanwhile, th...
Through consistent technological innovation, LONGi, the world's leading solar technology company, has achieved continual breakthroughs in PV conversion efficiencies, breaking the world record. World Record for Solar Cell Efficiency LONGi will continue to increase its investment in technology R&D and focus...
An effective way to improve polymer solar cell efficiency is to use a tandem structure, as a broader part of the spectrum of solar radiation is used and the thermalization loss of photon energy is minimized. In the past, the lack of high-performance low-

BEIJING, Feb. 21 (Xinhua) -- Chinese researchers have developed a type of perovskite solar cells (PSCs) with high power conversion efficiency. PSCs can be generally classified into two categories, n-i-p devices and inverted p-i-n devices. The p-i-n PSCs can be produced at low tempera...
iodine and organic materials to create an efficient cell with a small energy gap. "We developed a novel perovskite that absorbs lower-energy infrared light and delivers a 14.8 percent conversion efficiency," Eperon said. "We then combined it with a perovskite cell composed of similar materials bu...
N-type PERT (passivated emitter rear totally diffused) silicon solar cells promise high and stabilized conversion efficiencies. As relative big contact recombination and shading losses were introduced by traditional front screen-printed metallization, we applied Ni/Cu/Ag plating to form the front metalli...
Eventually, we report a series of certified power conversion efficiencies of up to 26.81% and fill factors up to 86.59% on industry-grade silicon wafers (274 cm2, M6 size).Similar content being viewed by others 27.09%-efficiency silicon heterojunction back contact solar cell and going beyond...
