Heterojunction solar cell
Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps. They are a hybrid technology, combining aspects of…
Colleen Bawn Solar Power Station
The Colleen Bawn Solar Power Station is a 32 MW (43,000 hp) solar power plant under development in Zimbabwe. The project is owned by Pretoria Portland Cement Limited, who own a cement factory in Colleen Bawn and plan to consume 16 megawatts of the electricity generated and sell the rest to the Zimbabwe national grid.
Solar power in Switzerland
Solar power in Switzerland has demonstrated consistent capacity growth since the early 2010s, influenced by government subsidy mechanisms such as the implementation of the feed-in tariff in 2009 and the enactment of the revised Energy Act in 2018. In 2025, solar power contributes nearly to 8 TWh of generation to the…
NASA-ESA Mars Sample Return
The NASA-ESA Mars Sample Return was a proposed Flagship-class Mars sample return (MSR) mission to collect Martian rock and soil samples in 43 small, cylindrical, pencil-sized, titanium tubes and return them to Earth around 2033. The NASA–ESA plan, approved in September 2022, was to return samples using three missions:…
Solar power in the United Kingdom
Solar power has a growing role in electricity production in the United Kingdom, contributing around 6.4% of the UK's annual power generation in 2025. As of 2025, on sunny days, it provides over 30% of the UK's power consumption at times.
Solar cell
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by using the photovoltaic effect. It is a type of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is…
40 Wall Street
40 Wall Street (also the Trump Building; formerly the Bank of Manhattan Trust Building and Manhattan Company Building) is a 927-foot-tall (283 m) neo-Gothic skyscraper on Wall Street between Nassau and William streets in the Financial District of Manhattan in New York City, New York, U.S. Erected in 1929–1930 as the…
Solar cell research
There are currently many research groups active in the field of photovoltaics in universities and research institutions around the world. This research can be categorized into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing…
