We experimentally demonstrate that monolithic perovskite/silicon tandem solar cells possess a superior reverse-bias resilience compared with perovskite single-junction solar cells. The majority of the reverse-bias voltage is dropped across the more robust silicon subcell, protecting the perovskite subcell from reverse-bias-induced degradation. These results

Perovskite solar cells have reached certified power conversion efficiency over 25%, enabling the realization of efficient large-area modules and even solar farms. It is therefore essential to deal with technical aspects, including the reverse-bias operation and hot-spot effects, which are crucial for the practical implementation of any photovoltaic technology. Here, we
Perovskite solar cells are likely to suffer more severe consequences than silicon cells when they become reverse biased such as due to partial shading. Resolution of the reverse-bias effect is critical to the large-scale application of these perovskites. Innovative approaches may be required since the intrinsic stabilities of these perovskites are unlikely ever to match

See my answer on the other comment for switching the light-sensing operation.

The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable reverse saturation current is a measure of the "leakage" of carriers across the p–n junction in reverse bias. This leakage is a result of carrier recombination in the neutral regions on

A light powered by the device. Scientists have created something of a reverse solar cell: a tool that generates electricity from the darkness of night. As energy and how humans produce it continues to be an important modern conversation, a team of researchers have branched way out, trying to harness energy from whatever sources they could.
Reverse solar panels generate electricity by harvesting heat energy in the form of infrared radiation as it is emitted from an outflow towards the sky. This is similar to how a solar cell absorbs solar radiation from the Sun.
Scientists are developing a new way to turn escaping nighttime heat into "reverse solar"-style energy. This isn't the only team to work on capturing low-wavelength radiation as a way to increase energy efficiency. The secret is using thermal radiation cells instead of photovoltaic solar cells.
The nighttime solar cells essentially work the same way as their daylight counterparts but in reverse. Every night, heat escapes the earth in the form of infrared radiation in order to keep the planet at a constant temperature.
The special solar cells work the same as their daytime counterparts - but in reverse. Specially designed panels could help solve the current problems with solar energy, by generating power once the sun has gone down. The panels were discovered in 2020, when scientists at the University of California Davis, US, hit the mainstream.
The findings have been published in a research paper. The nocturnal devices are able to generate up to 50 watts of power per square metre, a quarter of what conventional panels can generate in the daytime. They also work in the daytime if the light is blocked or if they are pointed away from the sun.
