Classic Application Series

The Classic Application Series offers a new opportunity to solve the old problem of limited power for wireless electronics designed for portable and remote applications. Classic Application panels are lightweight, paper-thin, and durable.

 

Their ultra-thin profile enables them to easy integration into devices for solar recharging or direct power. Panels have been specifically developed to recharge a variety of standard battery sizes. These panels do not have a UV-stabilized surface but are suitable for intermittent outdoor use.

 

Classic Application Series panels are optimized to collect sunlight outdoors and are a small representation of PowerFilm’s wide range of custom options including size, voltage and more.

 

These panels are well suited to power the wireless devices and sensors of the emerging IoT industry as well as many other electronics. Sizes range from inches to feet squared with a standard thickness of 0.22mm.

 

Power output is directly proportional to the surface area, with our smallest stock panel producing 70mW at 3V and our largest stock panel producing 1.54W at 15.4V. For permanent outdoor installations, a UV stabilized surface option is available. An edge seal can be added to make the panels weatherproof, or they can be mounted inside a clear weatherproof enclosure (see Encapsulation section for more information on weatherproofing, UV protection and other environmental options).

Prototyping

 

Connecting Electronic Component Panels In Series & Parallel

In general, PowerFilm always recommends a custom panel design rather than combining panels together. Although, for rapid prototyping and small quantities, panels can be connected together to increase the output voltage, current, and power to evaluate application requirements and conduct initial testing quickly. Panels can be connected in series to increase the output voltage or parallel to increase the output current.

 

Series Connection

The voltages of series-connected panels sum together, increasing the overall output voltage.

 

Series Connection Graphic

 

NOTE: For series connected panels, the current is limited by the panel which produced the lowest current. For this reason, only panels that output the same amount of current can be connected together in series.  

 

Parallel Connection

The current of parallel-connected panels sums together to increase the overall output current.

 

Parallel Connection Graphic

 

NOTE: Parallel connecting different voltage panels could cause damage to the panels. Only parallel connect panels with the same output voltage.


Encapsulation

PowerFilm has extensive knowledge of encapsulation and laminate technology. Based on environment and application needs, Powerfilm can recommend an encapsulation process to meet any requirement. Below are several common requirements that can be addressed by selecting the proper encapsulation.

 

UV Stability

For applications with extended exposure to direct sunlight, UV stable laminates are available for all Electronic Component Solar Panels. Alternatively, panels that are mounted in a clear UV resistant enclosure, would not require a UV stabilized Encapsulation.  

 

In general, for indoor and intermittent outdoor applications, UV stability is not required.

 

Weather Proofing

A weather sealing encapsulation can be added to any stock Electronic Component Solar Panels, making them completely weather and moisture-proof.

 

Electronic Component Solar Panels in the Classic Application Series and Indoor Light Series do not have moisture sealed edges. Over time direct contact with moisture, high humidity and temperature can cause corrosion to ingress from the edges of the panels.

 

The weather sealing process requires extra manual labor. Often mounting the panel in a clear weatherproof enclosure can be a cost-effective option.

 

In general, for indoor and intermittent outdoor applications, weatherproofing is not required.

 

Flexibility and Thickness

Electronic Component Solar Panel thickness ranges from 0.22 – 0.5+mm depending on the lamination stack used.

 

Standard Electronic Component Solar Panels have a minimum bend radius of 1 inch for fixed installations and 3 inches for repetitive flexing. In general, thinner laminates will be more flexible. Panels can be mounted onto a thicker substrate to increase rigidity.


Connections and Mounting

 

Connections

Positive and negative bus-bars are located on the sides of the panels and are currently available in 3/16” – 1/2” widths. Polarity can be determined by observing the orientation of the silver fingers which point from positive to negative.

 

 

Directly soldering wire leads to the busbars is the easiest way to connect to an Electronic Component Solar Panel. A soldering iron can be used to burn through the encapsulation layers to reach and connect to the busbar.

 

Exposed front or back-side contact options are available which make panels more compatible with large scale manufacturing and PCB mounting (see PCB Mounting and Connection for more information). These processes remove the encapsulation above or below the busbar to provide direct access for connection.  

 

An electrical connection can also be made using selective solder, conductive epoxies, conductive inks, conductive adhesives, z-axis adhesives, wire leads or manual soldering.

 

Bus-bars can also be extended outside of the encapsulation area to provide a connection.

 

Mounting

Electronic Component Solar Panels can be mounted via an adhesive bond, mechanical fasteners, or lamination (thermal adhesive) onto a substrate.

 

Panels are compatible with a wide range of adhesive materials including PSA, acrylic, butyl, VHB, and others. Peel and stick options are available.

 

A wide variety of mechanical fasteners such as rivets, grommets, screws, clamps, etc. can also be used for mounting. In general, make sure fasteners are at least ¼” away from active solar material and busbars.

 

Panels can also be laminated or vacuum-formed to plastic, metal, fiberglass, vinyl, fabric, carbon fiber, and other surfaces.

DO NOT PLACE PCB MOUNTED PANELS IN A REFLOW OVEN.

 

PCB Mounting and Connection

Electronic Component Solar Panels can be mounted to PC Boards using glue dots in addition to compatible methods mentioned above.

 

Placement onto a PCB can be made via tape and reel, robotic placement, or manual placement.

 

Electrical connection to a PCB can be made using selective solder, conductive epoxies, conductive inks, conductive adhesives, z-axis adhesives, wire leads or manual soldering.

 

 


Storage Elements and Charge Controllers

 

Battery Charging and Charge Controllers

Storage elements play an important role in a total power solution. Devices can store extra energy produced during sunny days and use it at night or on cloudy days. The most common storage elements are rechargeable batteries and capacitors/supercapacitors.

 

The way a storage element is charged varies widely for different technologies and material chemistries, so it is very important to understand what storage element you are using and how it is charged.

 

Rechargeable batteries have the strictest charging requirements which are unique for different battery chemistries; Li-Ion vs NIMH vs NiCd etc. IMPROPER CHARGING COULD RESULT IN FIRE OR EXPLOSION.

 

Capacitors and supercapacitors are much simpler to charge. They can be charged and discharged to any voltage under their rated max voltage. Although simpler, they usually have a much lower capacity and higher self-discharge when compared to rechargeable batteries.

 

For typical applications, a charge controller can be used to ensure safe and efficient charging. Many off the shelf charge controllers and reference designs exist for most storage element technologies.

 

A Max Power Point Tracking charge controller will extract the most power from our Electronic Component Solar Panels.

 

PowerFilm can recommend, source, or design charge controllers based on your application requirements.


Panel Sizing

 

Die Cutting

In general, the active solar material can only be manufactured into rectangular panels but the substrate around the panel can be die-cut into any desired shape.

 

Busbar tabs can also be included in the die-cut which could be folded underneath the panel (see below photos).

Sizing

Panels can be manufactured in a wide range of custom sizes spanning from less than a square inch up to multiple square feet.
