A facile method – graphene on silicon (G/Si) solar cells prepared by spray coating – is developed. The efficiency of spray-coated G/Si solar cells can reach 4.41%, comparable to that of conventional CVD-G/Si solar cells. This approach is done in air at low temperature, and is easy to scale up, making it appealing for the mass production of efficient and cost-effective G/Si solar cells.

ABSTRACTWe have recently observed that the initial performance of amorphous silicon (a-Si) solar cells can be improved by up to several % by annealing the cells at successively lower temperatures for successively longer times. For some devices, we also observed an improvement in performance after light soaking that was statistically significant. We have also observed an improvement in the stabilized performance of cells that were subjected to reverse bias annealing after light soaking. This effect was clearly evident in single-junction p-i-n cells with amorphous silicon-carbon (a-SiC) i-layers where the density of metastable centers is very high (> 1018cm-3). When we light-soaked a-SiC cells and then subjected them to low-temperature reverse bias annealing, they exhibited clear evidence of improved short-wavelength response after a second light soaking. These annealing effects are explained in terms of hydrogen motion within the a-Si network and within microvoids.

Besides silicon wafers, the metallization of solar cells is the most expensive process in the mass production of solar cells nowadays. Therefore, the development of cost-effective metallization technologies is very important for the reduction of manufacturing cost. In this article, we will introduce two novel approaches for the metallization of c-Si solar cells: (i) electroless plated Ni and electroplated Cu; (ii) photoplated Ni and Cu. It is believed that high efficiency and low cost solar cells can be fabricated taking advantages of the improved metallization methods.
