Mobile flexible thin film solar charger

In today's military operations and outdoor exploration fields, reliable power supply is crucial for the normal operation of various equipment. Whether it's drones soaring in the sky to carry out reconnaissance missions, walkie talkies ensuring communication, night vision devices providing soldiers with a field of view in the dark, or other electrical devices in individual equipment, continuous and stable power is required. The emergence of solar flexible thin film chargers provides a highly innovative solution to solve the charging problems of these devices.

The solar flexible thin film charger is mainly based on the principle of photovoltaic effect. Its core is a thin film composed of multiple layers of semiconductor materials. When sunlight shines on these thin films, the energy of photons is absorbed by electrons in the semiconductor material, causing electrons to transition from the valence band to the conduction band, thereby generating electron hole pairs. These freely moving electrons and holes move towards the two ends of the electrode under the action of an internal electric field, forming a potential difference and generating an electric current. Unlike traditional solar panels, flexible thin film chargers use special materials and manufacturing processes, making them flexible and lightweight. This type of film can be adhered to surfaces of various shapes of objects, maximizing the use of light exposure area and improving power generation efficiency.

Application of solar flexible thin film charger in unmanned aerial vehicles (UAV)

Drones play an important role in military reconnaissance, border patrol, disaster monitoring, and other fields. However, its limited battery life has always been a key factor limiting its long-term operation. The solar flexible thin film charger can be cleverly integrated into the surfaces of the wings, fuselage, and other parts of unmanned aerial vehicles. During the flight, the drone battery can be continuously charged even in low sunlight conditions. For example, in some long-distance border patrol missions, drones can use the daylight hours during flight to replenish power, effectively extending flight time and reducing frequent battery replacement or charging due to low battery levels, greatly improving the efficiency of mission execution.

In some complex environments, such as mountainous areas, jungles, etc., drones may not be able to return to the base for charging in a timely manner due to unexpected situations. The solar flexible thin film charger has now become an emergency charging method. Even if the drone runs out of battery and makes an emergency landing during the mission, as long as there is sunlight, it can continue to receive electrical energy, providing the possibility for re takeoff or waiting for rescue, ensuring the safety of the drone and the sustainability of the mission.

Application in walkie talkies

a.  Continued communication guarantee

Interphone is a key device for maintaining communication in military operations, outdoor exploration teams, and other scenarios. During prolonged operation, the depletion of battery power can lead to communication interruption, which may have serious consequences. The solar flexible thin film charger can be combined with the outer shell design of the walkie talkie, or used in conjunction with the walkie talkie in the form of a backpack or other external accessories. During the operation, whether marching or camping in the wilderness, as long as there is sunlight, the walkie talkie can be charged to ensure continuous communication. Especially in military exercises or long-term outdoor exploration activities in remote areas, this continuous charging capability provides a solid guarantee for communication between teams.

b.  Reduce logistical burden

The traditional charging method for walkie talkies requires carrying a large number of backup batteries and charging equipment, which increases the workload of the operation. The application of solar flexible thin film chargers reduces reliance on backup batteries, allowing soldiers or explorers to carry fewer charging devices and batteries, thereby reducing logistical burden and improving mobility and flexibility of operations.

Application in night vision devices

a. Nighttime combat energy replenishment

Night vision goggles are important equipment for modern military night operations, and are crucial for soldiers' observation and combat capabilities in dark environments. But the high energy consumption of night vision devices often limits their continuous use time. The solar flexible thin film charger can collect solar energy and store electrical energy during the day to charge night vision devices used at night. This charging method can ensure that the night vision device has sufficient power before the start of night operations, and in some special situations, such as long-term nighttime stealth missions, if there is weak lighting conditions such as moonlight, the solar flexible film charger can also supplement the power of the night vision device to a certain extent, maintain its normal operation, and improve the efficiency of soldiers in night combat.

b. Concealed combat advantage

In some military missions that require covert operations, using traditional charging methods may expose targets. The solar flexible thin film charger can use natural lighting for charging without the need to connect to an external power source, reducing the risk of being discovered by the enemy due to electromagnetic signals or other characteristics of the charging device, and providing certain advantages for covert operations.

Application in other electrical appliances of individual soldier equipment

a. Integrated charging function

Other electrical devices in individual soldier equipment, such as GPS locators and tactical tablets, require stable power supply. The solar flexible thin film charger can be designed as a multifunctional charging equipment, and soldiers can connect various devices that need to be charged to the charger through appropriate interfaces. During outdoor marching, combat, and other processes, solar energy can be used to charge these devices, whether during movement or brief rest, achieving the integration of energy supply for individual equipment and improving soldiers' efficiency and combat capabilities in using various equipment.

b. Adapt to complex environments

Individual soldiers may face various complex environments during task execution, such as high temperature, low temperature, humidity, etc. The solar flexible thin film charger adopts advanced materials and packaging technology, which can work normally under these harsh environmental conditions. Its flexible characteristics also make it less likely to be damaged by collisions, squeezes, and other situations during soldier operations, and it has strong environmental adaptability, providing reliable charging support for electrical equipment in individual soldier equipment.
