SETO FY2018 – Photovoltaics

You are here

The Solar Energy Technologies Office Fiscal Year 2018 (SETO FY2018) funding program addresses the affordability, flexibility, and performance of solar technologies on the grid. This program funds early-stage research projects that advance both solar photovoltaic (PV) and concentrating solar-thermal power (CSP) technologies and supports efforts that prepare the solar workforce for the industry’s future needs.

On October 23, 2018, the U.S. Department of Energy announced it would provide $53 million in funding for 53 projects in the SETO FY2018 funding program. Of those projects, 31 will focus on photovoltaics research and development. Read the announcement.

Approach

Projects in the photovoltaics research and development topic support early-stage research that increase performance, reduce materials and processing costs, and improve reliability of PV cells, modules, and systems to enable the industry to achieve its 2030 cost goals.

Within the PV topic, the office has also selected projects that will develop and test new ways to accelerate the integration of emerging technologies into the solar industry. These Innovative Pathway projects do not fund individual technologies along their pathway to market, but instead focus on improving the pathway itself.

Objectives

Projects in this funding program will strengthen the innovation ecosystem across the country and work toward achieving the office’s 2030 cost targets. Technical projects will work toward developing new technologies and solutions capable of lowering solar electricity costs for PV, while Innovative Pathway projects will work toward creating new ways to overcome technology transfer challenges.

Cost Share: $69,113
Principal Investigator: Julia Hsu
Project Summary: In collaboration with NovaCentrix, this team will apply photonic curing to the thermal annealing process needed to form and optimize the layers in a perovskite solar cell. Photonic curing can replace the lengthy, costly, and energy-intensive conventional heating methods that are not compatible with high-throughput manufacturing on flexible substrates. The goal of this project is to increase manufacturing throughput and lower manufacturing costs while maintaining the performance metrics needed to establish a clear path toward the $.03 cents per kilowatt-hour by 2030 for utility-scale solar.

Washington State University

Project Name: Preparation and Evaluation of N-type CdSeTe as an Absorber in Thin-Film CdTe PV
Location: Pullman, WA
DOE Award Amount: $198,578
Cost Share: $49,645
Principal Investigator: Kelvin Lynn
Project Summary: The power-conversion efficiency of conventional p-type cadmium telluride absorbers is limited by relatively poor electronic properties, including low carrier lifetime, low doping levels, and challenges with back contact formation.

Location: Minneapolis, MN
DOE Award Amount: $200,000
Cost Share: $50,000
Principal Investigator: Vivian Ferry
Project Summary: Silicon-based photovoltaic modules operate at elevated temperatures, which can reduce the lifetime of a photovoltaic module and contribute to thermal degradation. One of the major sources of elevated temperature is the low-energy infrared light that is converted to heat within the cell. This project aims to replace the silicon nitride antireflection coating that’s used on solar cells with spectrally selective photonic structures. The new design will enable the structures to capture usable photons while rejecting those that lack the energy to produce electricity, resulting in improved energy yield for solar cells. The structures will be integrated on the top surface of the cell to avoid damage from weathering and will be fabricated with fewer layers to minimize cost.

Project Name: Controlling the Recombination Activity of Dislocations in III-V Solar Cells
Location: Urbana, IL
DOE Award Amount: $200,000
Cost Share: $50,000
Principal Investigator: Minjoo Lee
Project Summary: Existing III-V manufacturing methods, such as epitaxial liftoff, that attempt to reuse costly III-V and germanium substrates over many growth cycles are too expensive to enable manufacturing at scale. One way to overcome this issue is to grow them on low-cost substrates such as silicon. This team will perform the first systematic study of III-V solar cells grown on silicon surfaces decorated with beryllium, carbon, germanium, tellurium, and other impurities in order to identify conditions that will render dislocations and other structural defects less harmful to solar cell performance. Reducing the impact of defects would improve device performance and enable the use of low-cost growth substrates in the fabrication of high-performance III-V cells and modules.

Principal Investigator: Andre Augusto
Project Summary: This team will investigate the potential advantages of using undoped silicon wafers to make high-performance solar cells. The team will examine silicon heterojunction cell characteristics built using wafers with a range of low n- and p-type dopant concentrations, and will closely observe the transition from low-level to high-level injection in order to better understand the device physics of these cells. These studies could impact the manufacturing yield of Czochralski-grown wafers for which dopant concentration varies along the length of the ingot, and will help to better understand the effects of doping levels on light and polarization-induced degradation mechanisms. This research aims to lower the levelized cost of energy by improving photovoltaic cell and ingot manufacturing yield, silicon cell power output, and module reliability.

DNV GL

Project Name: Bifacial PV Module Energy Modeling Validation Study

DOE Award Amount: $200,000
Cost Share: $50,000
Principal Investigator: Tara Doyle
Project Summary: Bifacial photovoltaic (PV) module suppliers are conducting their own efficiency tests in an effort to demonstrate energy gains to customers, but these tests often lack third-party review. To enable more accurate and bankable solar production forecasts for bifacial modules, this team will establish an outdoor test that compares modeled energy from bifacial models to measured energy generation in common types of ground or roof coverings. These tests will account for multiple scenarios for bifacial modules, including placement on painted flat roofs, placement in fields with low-lying vegetation, and soiling from dirt or sand. The team will publish the results of this analysis to improve modeling efforts, energy-yield estimates, and bankability for bifacial modules on the market.

Project Name: Towards 50 Year Lifetime PV Modules: Glass/Backsheet vs. Double Glass
Location: Cleveland, OH
DOE Award Amount: $1,350,000
Cost Share: $337,500
Principal Investigator: Roger French
Project Summary: In order to enable photovoltaic (PV) modules to have a 50-year lifetime, researchers are exploring PV modules with double glass or glass/backsheet designs.

Cost Share: $280,000
Principal Investigator: Jeong-Mo Hwang
Project Summary: This team developed a low-cost plasma-charging technology that can be used for field-effect passivation in crystalline silicon solar cells and to increase efficiency. The technology uses an inexpensive inert gas plasma that does not cause film deposition or corrosion inside the chamber during charging and does not require regular cleaning of the chamber. To enable the commercial use of this tool, the team will work to mitigate the loss of injected charges during the high-temperature metal-firing process and increase the stability of injected charges by mitigating optical and electronic degradation pathways. These efforts have the potential to enable contact deposition that matches the high performance of aluminum oxide while maintaining the low production costs of conventional passivation materials.

Novel amorphous silicon contacts applied to cadmium telluride absorbers will be characterized using multiple bulk and interface loss-analysis methods. Using this methodology, the team will examine a wider range of absorber materials and create a platform that enables users to rapidly and accurately assess the quality of a wide range of bulk materials and surface passivation layers, including contact selectivity and contact resistivity. 

Arizona State University 4

Project Name: Reliability Evaluation of Bifacial and Monofacial Glass/Glass Modules with Ethylene Vinyl Acetate (EVA) and Non-EVA Encapsulants
Location: Tempe, AZ
DOE Award Amount: $1,500,000
Cost Share: $375,000
Principal Investigator: Govindasamy Tamizhmani
Project Summary: Photovoltaic modules with glass/glass encapsulation are expected to be more resistant to breakage and degradation than glass/backsheet modules. However, many glass/glass-module architectures continue to use ethylene vinyl acetate (EVA) as an internal encapsulant, and EVA has been linked to significant life-limiting reliability issues, including glass cracking, encapsulant delamination, and encapsulant browning. This project will assess the merits and shortcomings of glass/glass modules with EVA and non-EVA encapsulants by evaluating new and field-aged modules. The team will then evaluate the expected reliability of these modules using indoor and outdoor accelerated tests.
