Primarily current. Photons release electrons, which flow in the form of current. That current divides itself between two current sinks in parallel: a weakly forward-biased diode (i.e. the solar cell itself) and the external load on the terminals.
The problem is there are three variables voltage, current (which are dependent on the load) and the amount of power received by the cell. So, you need a circuit that can track the maximum peak power point (MPP Tracking or MPPT) to get the best efficiency from the solar cell.
A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.
For Advanced Users – Since these cells are in series, the current through each of the cells is the same. In any set of solar cells, there is a distribution of physical properties that determine solar cell efficiency. As a result, there is a distribution of efficiencies.
Photovoltaic cells and solar collectors are the two means of producing solar power. Assemblies of solar cells are used to make solar modules that generate electrical power from sunlight, as distinguished from a "solar thermal module" or "solar hot water panel". A solar array generates solar power using solar energy.
Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as "solar panels". Almost all commercial PV cells consist of crystalline silicon, with a market share of 95%. Cadmium telluride thin-film solar cells account for the remainder.

Perovskite solar cells are solar cells that include a perovskite-structured material as the active layer. Most commonly, this is a solution-processed hybrid organic-inorganic tin or lead halide based material. Efficiencies have increased from below 5% at their first usage in 2009 to 25.5% in 2020, making them a very rapidly advancing technology and a hot topic in the solar cell field.
