The present disclosure relates to a tandem solar cell, a tandem solar cell module comprising the tandem solar cell, and a method for manufacturing the same. More specifically, the present disclosure relates to a monolithic tandem solar cell comprising a perovskite solar cell laminated on a front surface of a crystalline silicon solar cell, and a method for manufacturing the same.

According to the present disclosure, a Nano-electrode structure can be patterned on a front surface of a front transparent electrode of a solar cell in which a crystalline silicon solar cell and a perovskite solar cell are bonded via a junction layer, such that the optical path of the sunlight incident on the solar cell through the Nano-electrode structure can be increased to improve the utilization rate of the light.

A wireless self-charging power pack including a solution processed conductive thin film integrating a solar cell with a solid-state supercapacitor. Additionally, a method of forming a wireless self-charging power pack including integrating a solar cell with a solid-state supercapacitor by forming a layer of conductive thin film between the solar cell and the solid-state supercapacitor through solution processing of the material forming the conductive thin film.

A three-tandem (3T) perovskite/silicon (PVT)-based tandem solar cell (TSC) includes an antireflection coating (ARC), a first transparent conductive oxide layer (TCO), a hole transport layer (HTL), a perovskite (PVT) layer, a second transparent conductive oxide layer (TCO), an electron transport layer (ETL), a plurality of buried contacts, a p-type Si layer, a p-type wafer-based homo-junction silicon solar cell, a n.sup.+ silicon layer, a back contact layer. The solar cell further includes a top sub-cell, a bottom sub-cell and a middle contact-based tandem. The top sub-cell includes the PVT layer. The bottom sub-cell includes the silicon solar cell. The middle contact-based tandem includes the second TCO layer to be used as the middle contact-based tandem, as well as a recombination layer for current collection. Further, a conduction and a valence band edge are employed at a front surface of the ETL.

A photovoltaic device includes one or more features that taken alone or in combination enhance its efficiency. Some embodiments may comprise a tandem solar device in which a top PV cell is fabricated upon a front transparent substrate, that also serves as the top encapsulating substance. The top PV cell including the front encapsulating substance is then bonded (e.g., using adhesive) to a bottom PV cell in order to complete the tandem device. Using the same transparent, insulating element as both front encapsulating substance and a substrate for fabricating the top PV cell, obviates to the need to provide a separate structure (with resulting interfaces) to perform the latter role. For tandem and non-tandem PV devices, a Through-Substrate-Via (TSV) structure may extend through an insulating substrate in order to provide contact with an opposite side (e.g., back electrode). Embodiments may find particular use in fabricating shingled perovskite photovoltaic solar cells.
