Definitions

  • the present invention relates to printed solar cells, and more specifically to a printed solar cell comprising a cell body and edge portions.
  • a printed solar cell also known as a wet processed solar cell, is a type of solar cell that uses organic or hybrid organic electronics.
  • Organic electronics is a branch of electronics that deals with conductive organic polymers or small organic molecules for light absorption and charge transport to produce electricity from light by the photovoltaic effect.

  • Such a solar cell may be a perovskite solar cell which includes a perovskite-structured compound as the light-harvesting substrate.
  • Printed solar cells are becoming ever more efficient, and thus their applications increase rapidly.
  • Printed solar cells are light energy harvesting modules that may not only harvest sunlight, but may also beneficially harvest artificial light indoors.
  • Printed solar cells may thus power low-power applications such as small electric appliances that previously required batteries.
  • Printed solar cells may also be applied in addition to batteries.
  • Printed solar cells manufactured using low-cost adhesives are commonly provided with a wide border or edge portions of barrier foil around the cell body.
  • the edge portions provide adhesion between the barrier foils, and provide a buffer against water and oxygen ingress through the sides.
  • Printed solar cells are commonly sensitive to moisture and oxygen ingress, and wide edge portions thus provide a more robust printed solar cell. Wide edges also improve the production tolerances, and the risk of manufacturing defects is reduced, thus increasing production yield.
  • Printed solar cells comprising narrow barrier foil edge portions around the cell body are commonly more exposed to malfunction, exhibit less resilience and also increase the risk of lower yield in production.
  • Printed solar cells may preferably be mounted on top of a printed circuit board or similar device. Conducting the power generated by a traditional printed solar cell to the printed circuit board may require an additional manufacturing step, and as such be a time consuming and cumbersome process.

  • the cell body comprises a first foil of a transparent flexible substrate with a printed semiconductor laminated onto a second foil of a transparent flexible substrate with a printed semiconductor.
  • two edge portions protrude at an angle relative to the cell body, each edge portion comprising a printed contact bridge for conducting electric current from the printed semiconductor.
  • contact points are provided at the two edge portions comprising a printed contact bridge.
  • the printed contact bridge is encapsulated by the barrier foils and the contact points pierce the barrier foils.
  • the contact points are conducting arm elements angled relative to a plane of a corresponding edge portion and protrudes on an underside of the cell body.
  • the printed solar cell comprises a cut out where two adjacent edge portions meet, for providing a smaller footprint and accommodating the angled edge portions.
  • the at least one edge portion protrudes at an angle approximately 90° relative to the cell body.
  • a method of forming at least one angled edge portion of a printed solar cell comprising a cell body comprising a semiconductor printed on a flexible substrate encapsulated by barrier foils, the method comprising the steps of: heating at least an edge portion of the printed solar cell; bending the at least one edge portion relative to the cell body.
  • the method further comprising a step of removing material from where two adjacent edge portions meet prior to the step of heating at least an edge portion, in order to accommodate bending of the edge portions.
  • the step of heating further comprises heating the at least edge portion up to approximately 80° Celsius.
  • the step of bending comprises bending the at least one edge portion until it is bent approximately 90° relative to the cell body.

  • a bottom layer may comprise a printed semiconductor 6 printed onto a flexible substrate 7, and a top layer may comprise a printed semiconductor 6 printed onto a flexible substrate 7.
  • the two layers may be merged by laminating the printed semiconductors 6 facing each other.
  • the top and bottom layers are then encapsulated by adding top and bottom barrier foils 8. As previously described, the barrier foils 8 extend further out than the printed semiconductor 6, such that the top and bottom barrier foils 8 are fixed together around the cell body 4 and form the edge portions 5.
  • Figure 7 shows a top view of a further embodiment of a printed solar cell 2 prior to the edge portions 5 being angled relative to the cell body 4.

Contacting of the solar cell may therefore also be performed below the cell body 4 and will thereby not affect the footprint either.
  • Figure 9 illustrates another embodiment, with only one printed semiconductor 6 area.
