METHOD OF PROCESSING INCONSISTENCIES IN SOLAR CELL DEVICES AND DEVICES FORMED THEREBY
The present disclosure is directed to a method of processing a solar cell device. The method comprises detecting at least one inconsistency at a surface of a semiconductor substrate having a solar cell active region formed therein. A deposition pattern is determined based on the location of the at least one inconsistency. A material is selectively deposited on the substrate according to the deposition pattern.
Two-dimensional semiconductor based printable optoelectronic inks, fabricating methods and applications of same
Printable inks based on a 2D semiconductor, such as MoS2, and its applications in fully inkjet-printed optoelectronic devices are disclosed. Specifically, percolating films of MoS2 nanosheets with superlative electrical conductivity (10-2 s m−1) are achieved by tailoring the ink formulation and curing conditions. Based on an ethyl cellulose dispersant, the MoS2 nanosheet ink also offers exceptional viscosity tunability, colloidal stability, and printability on both rigid and flexible substrates. Two distinct classes of photodetectors are fabricated based on the substrate and post-print curing method. While thermal annealing of printed devices on rigid glass substrates leads to a fast photoresponse of 150 μs, photonically annealed devices on flexible polyimide substrates possess high photoresponsivity exceeding 50 mA/W. The photonically annealed photodetector also significantly reduces the curing time down to the millisecond-scale and maintains functionality over 500 bending cycles, thus providing a direct pathway to roll-to-roll manufacturing of next-generation flexible optoelectronics.
Method for the production of a light-to-electricity converter made entirely from silicon for a giant photoconversion
The production process according to the invention consists of a nanometric scale transformation of the crystalline silicon in a hybrid arrangement buried within the crystal lattice of a silicon wafer, to improve the efficiency of the conversion of light into electricity, by means of hot electrons. All the parameters, procedures and steps involved in manufacturing giant photoconversion cells have been tested and validated separately, by producing twenty series of test devices. An example of the technology consists of manufacturing a conventional crystalline silicon photovoltaic cell with a single collection junction and completing the device thus obtained by an amorphizing ion implantation followed by a post-implantation thermal treatment. The modulation of the crystal, specific to the giant photoconversion, is then carried out on a nanometric scale in a controlled manner to obtain SEGTONs and SEG-MATTER which are active both optically and electronically, together with the primary conversion of the host converter.
