Thin-film, lightweight, large-area flexible inorganic solar cells have shown promise to meet the militarys remote power needs on the battlefield. However, thin film solar cells normally have inferior conversion efficiencies due to limited absorption of sunlight by the thin active layer. Various approaches have been investigated to improve conversion efficiencies of thin film solar cells. Among these approaches, metallic nanostructure induced light scattering or trapping in the thin films have been demonstrated as an effective approach. Another approach to enhance solar cell efficiencies is a broadband, wide angle anti-reflective coating. Therefore, it will be ideal if a coating can perform multi-functions: top electrode, AR coating, and scattering long wavelengths into the solar cell. Leveraging its previous development of high performance flexible solar cells for Small Unmanned Aerial Vehicles, Agiltron proposes to develop nanostructured multi-functional top coatings for flexible thin film inorganic solar cells. The proposed top electrode can be readily applied on flexible thin film solar cells to achieve short-circuit current improvement by a factor of 25%. Phase I of this program is to demonstrate the technical feasibility through modeling, analysis, and experimentation.

Agiltron in collaboration with National Renewable Energy Laboratory (NREL) will develop a new class of high-efficiency and lightweight broadband inverted metamorphic multi-junction (IMM) solar cells for the uninterrupted flight missions of unmanned aerial vehicles (UAVs). The approach is closely coupled with Agiltrons extensive experience in high-transmittance broadband and wide-angle anti-reflective microstructures and NRELs significant progress in high efficiency IMM solar cells to push the cells conversion efficiency performance well beyond the current state-of-the-art. The novel solar cells will be transferred from thick, heavy, and stiff substrates to a thin, light and flexible support handle, thus meeting the NAVYs specific-power requirement. This novel solar cell technique has several unique advantages over conventional approaches, including high conversion efficiency, high specific power, wide incident angle acceptance, broad band operation, and high flexibility. The technical approach has been proven in Phase I through numerical analysis, simulations and experiments. The solar cell array module prototype will be designed, fabricated, characterized, and delivered to the Navy in Phase II.

A Neutron detection device is an indispensable tool for Homeland Security, defense, power and medical applications. The proliferation of weapons of mass destruction such as nuclear weapons is a serious threat in today's world. Low cost, low power, high performance, rugged and portable neutron detection devices are highly desirable for these applications. Yet, the cost and production volume of the traditional He-3 tube based neutron detector are greatly limited by the availability of He-3 rare gas. Agiltron proposes an unprecedented fabrication and integration approach to make a boron-10 filled micro-fabricated 3D solid-state neutron detector, which, with performance comparable to He-3 tubes, can be commercially manufactured at low cost for large-scale deployment and will replace the LiI detector used in current personal radiation detectors (PRD). Our success in Phase I will demonstrate the feasibility of key fabrication steps and provided a rationale for carrying out the detector module development in Phase II, which will further lead to the large-scale manufacture of these next generation neutron detectors.

A compact and effective 10-micron femtosecond laser with pulse duration <500fs and repetition rate of 100Hz or smaller is desirable by DOE for seeding CO2 ultrafast laser systems to improve the stability, reliability and efficiency in generating 10-micron laser from GW up to 100TW peak power, which is irreplaceable in driving an accelerator for particle beam generation due to the efficiency proportional to the square of the laser wavelength. Agiltron proposes a fiber based ultrafast 10-micron seed laser that can provide the required specifications and high performance. Its success will directly benefit DOEs compact proton and ion sources. The innovative technology can be used for ultrafast laser generation over the whole mid-IR range, and speed up the development of mid-IR laser applications.Agiltron, Inc. has successfully completed all tasks and demonstrated the feasibility of a fiber based 10-micron ultrafast laser in Phase I of the Program. We built a mode-locked fiber laser that generated < 400fs ultrafast laser pulses and successfully controlled the repetition rate to be the required 100Hz. Using this mode-locked laser, we demonstrated the feasibility of parametric femtosecond laser generation based on frequency down conversion. The experimental results agree with our simulation results. The investigation results of Phase I will be used to optimize the design of the laser system and build a fully functional prototype for delivery to the DOE in the Phase II program. The prototype development in Phase II program will be in the collaboration with Professor Chandrashekhar Joshi, the leader of UCLA Laser-Plasma group. Prof. Joshi discovered a new mechanism for generation of monoenergetic proton/ion beams: Shock Wave Acceleration in a near critical density plasma and demonstrated that high-energy proton beams using CO2 laser driven collisionless shocks in a gas jet plasma, which opened an opportunity to develop a rather compact high-repetition rate ion source for medical and other applications which could be significantly cheaper than that based on RF acceleration. We propose an output energy >1 J, one order of magnitude higher than the DOE original requirement. The performance of the prototype will be tested at UCLA by directly seeding the CO2 laser system driving an accelerator.

Agiltron proposes a new type of portable inductively coupling wireless battery charger station to relieve the logistic footprint and operation complexity of the wired power connection for charging battery-operated devices in the battlefield management. The wireless battery charger station will allow power transfers greater than 5 meters from the charging source with efficiency more than 50%. The power transmitter subsystem will weigh less than 10 kg with the maximum diameter of 0.15m. The portable receiver/battery charger subunit will weigh less than 6 kg. Power can transfer through many common materials like tent canvas and plywood. The system is low cost, robust and easy to maintenance. In Phase II, the design, fabrication, and power transfer and evaluation testing will be performed for prototypes of the wireless battery charger. Higher-volume production is expected in Phase III for delivery to the Army and other customers.
