TL;DR: A photovoltaic device comprising an amorphous silicon-containing i-layer that is more efficient at elevated operation temperatures than at lower operation temperatures was proposed in this paper.

TL;DR: The temperature behavior of amorphous silicon (a-Si) based solar cells was measured for cells made under different fabrication conditions and with different thermal and illumination histories in this article.

TL;DR: In this paper, all-laser-transferred contacts (ALTC) have been used for the fabrication of crystalline silicon solar cells with both front and rear metallization achieved through laser induced forward transferring.

TL;DR: In this article, the effect of several physical parameters (bulk lifetime, substrate doping, emitter fraction and surface recombination velocity in the gap between the emitter and BSF) on solar cell performance was explored using the SENTAURUS DEVICE™ program (formerly DESSIS) and it was found that efficiencies in excess of 22 and 20.8 percent can be achieved on p and n type substrates respectively with a bulk lifetime of 300 microseconds.

TL;DR: The significant advances in high-power lasers with the attainment of tens of kilowatts of optical power, high repetition rates (>MHz), reduction in size, lower cost per photon ( 30%), and significant advances for material processing with very high throughput are driving the use of lasers for materials processing for renewable energy materials as discussed by the authors.
